12.2x8.54m Adjustable-Height Steel Ringlock Stage Platform with 4x8ft Wooden Decks and Dual Stairs
This structure is a 12.2m × 8.54m modular temporary stage platform built on a steel Ringlock support system and covered by 35 modular 4 × 8ft (1.22 × 2.44m) wooden-topped stage panels.
Unlike a stage designed around only one fixed elevation, the original configuration provides several platform-height options:
0.4–0.6m;
0.6–1.0m;
0.8–1.2m;
1.0–1.5m;
1.5–2.0m.
The confirmed system also includes 48 adjustable base positions and two 5-step stage stairs.
On DragonStructure, however, the useful question is different:
How are 4x8ft stage panels, Ringlock vertical supports, horizontal members, adjustable bases and stairs organized into one 12.2x8.54m elevated stage—and what changes when the platform height changes?
The primary function of this structure is to create a:
large temporary elevated event platform
using a modular steel supporting framework underneath a repeatable deck system.
The basic relationship is:
Ground / Supporting Surface
↓
Adjustable Bases
↓
Steel Ringlock Vertical Supports
↓
Horizontal Members
↓
Forks + Clamps / Upper Support Interface
↓
4 × 8ft Stage Panels
↓
12.2 × 8.54m Elevated Stage Surface
Two stair units provide access between ground level and the finished platform.
This is a practical system breakdown based on the supplied configuration. It should not be interpreted as a calculated structural load path.
2. Overall Stage Geometry
The confirmed overall stage dimensions are:
12.2m × 8.54m
giving a nominal rectangular footprint of approximately:
104.2m²
The upper surface uses:
35 pcs × 4 × 8ft stage panels
with the metric panel dimensions listed as:
1.22m × 2.44m
One panel therefore has a nominal area of:
1.22 × 2.44 ≈ 2.98m²
and 35 panels provide approximately:
104.2m²
of nominal deck area.
This corresponds closely with the overall 12.2 × 8.54m platform dimensions recorded on the original product page.
The relationship is therefore not accidental:
35 standardized panels
become approximately:
104m² of continuous stage surface.
3. The 4x8ft Deck Matrix
The upper platform is based on a particularly simple module:
4 × 8ft
or approximately:
1.22 × 2.44m
Because:
12.2m ÷ 2.44m = 5
and:
8.54m ÷ 1.22m = 7
the platform can be understood as a:
5 × 7 deck matrix
giving:
5 × 7 = 35 panels
This matches the confirmed BOQ exactly.
Conceptually:
5 deck lengths × 7 deck widths
↓
35 modular panels
↓
12.2m × 8.54m platform
This is one of the clearest structural characteristics of the product.
Rather than treating 12.2 × 8.54m as an arbitrary custom dimension, the overall platform is generated directly from the dimensions of the repeated deck module.
4. Main Structural Modules
The complete structure can be divided into five functional groups.
These panels form the continuous usable stage area.
B. Vertical Ringlock Support
The supplied BOQ lists:
LR01 pillar and inner tube L = 1.40m 48 pcs
These components form the main vertical support positions beneath the stage.
The exact assembled height is not determined by the 1.40m component length alone because the product is sold in several different finished-height ranges.
Therefore the 1.40m pillar dimension should not be interpreted as meaning that every version of this stage is exactly 1.40m high.
C. Horizontal Support Grid
The supplied configuration includes two horizontal-member lengths:
LR02 horizontal pipe, 8ft — 80 pcs
and
LR02 horizontal pipe, 4ft — 84 pcs.
This again reflects the 4 × 8ft dimensional logic used by the deck system.
The upper deck geometry and the lower supporting framework therefore share a common modular language:
4ft
and
8ft.
That makes the platform easier to understand as one coordinated system rather than separate deck and scaffold products.
D. Upper and Lower Adjustment / Connection Components
The confirmed BOQ includes:
Fork — 48 pcs;
Clamp — 40 pcs;
Stage adjustable base — 48 pcs.
These components connect and adjust different parts of the stage support system.
At the lower level, adjustable bases provide practical elevation adjustment.
At the upper level, forks and clamps form part of the interface between the supporting framework and stage platform.
The exact structural capacity of these connections is not established by the supplied page and should be verified separately where required.
E. Stair Access
The system includes:
2 stage stairs
with:
5 steps per stair
and:
wooden topping.
These stairs connect the elevated working surface to ground level.
Their exact installed positions are not specified in the source, so they should be treated as configurable access modules rather than assuming a front-left/front-right arrangement.
5. Why the 4ft and 8ft Dimensions Matter
The strongest modular relationship in this stage is the repetition of:
4ft × 8ft
across both the platform and supporting system.
The deck is:
4 × 8ft
while the Ringlock horizontal members include:
4ft members
and:
8ft members.
This allows the upper and lower systems to follow the same dimensional rhythm.
In simple terms:
deck dimensions define the surface grid
while:
horizontal support dimensions follow that grid underneath.
This is a useful example of modular structure design: instead of designing the support system first and trying to fit the deck later, the deck module and support module are coordinated.
6. 48 Main Support Positions
The BOQ contains the same quantity—48 pcs—for several support-related components:
LR01 pillar and inner tube — 48 pcs;
Fork — 48 pcs;
Stage adjustable base — 48 pcs.
This indicates a repeated vertical support arrangement in the supplied configuration.
The practical relationship can be understood as:
Adjustable Base
↓
Vertical Support / Pillar
↓
Upper Fork
↓
Horizontal / Platform Interface
The exact tributary area, allowable load per support and engineering capacity are not supplied in the original product information, so no such values should be inferred from the component count.
7. Adjustable Platform Height
This is the most distinctive feature of this particular Ringlock stage.
The original product offers five height ranges:
Height Option
Confirmed Range
Option 1
0.4–0.6m
Option 2
0.6–1.0m
Option 3
0.8–1.2m
Option 4
1.0–1.5m
Option 5
1.5–2.0m
These are product configuration ranges from the source page, not a statement that one assembled stage can simply be moved continuously from 0.4m to 2m without changing components.
That distinction matters.
A better way to understand the product is:
Same Stage Footprint
Different Vertical Configuration
=
Different Finished Platform Height Range
8. What Changes When Stage Height Changes?
The 12.2 × 8.54m upper platform can remain the same while the vertical structure underneath changes.
Conceptually:
12.2 × 8.54m deck matrix
can remain constant,
while:
vertical support arrangement + adjustment components + access configuration
change according to platform height.
The source page itself confirms that the different height options have different packing weights.
That is strong practical evidence that the height options are not merely a matter of turning an adjustable base higher or lower.
They represent different supplied configurations.
9. Packing Differences Between Height Configurations
The original product provides the following packing information:
Platform Height Range
Packing Weight
Packing Volume
0.4–0.6m
3,100kg
14m³
0.6–1.0m
3,620kg
14.5m³
0.8–1.2m
3,625kg
14.6m³
1.0–1.5m
3,630kg
15m³
1.5–2.0m
3,780kg
15m³
This table reveals something structurally useful.
The platform footprint remains 12.2 × 8.54m, but the shipped system changes as height increases.
That means:
Stage height is a structural configuration variable, not merely a cosmetic dimension.
It affects the supporting component package and therefore also affects packing weight and volume.
10. Why Height Should Be Confirmed Before the BOQ
For this type of structure, saying:
“I need a 12.2 × 8.54m stage”
is not enough to determine the complete supply configuration.
You also need:
“I need the platform approximately ___ m above ground.”
Because:
same width + same depth
does not necessarily mean:
same supporting structure.
The source itself demonstrates this through five different height configurations.
Therefore the practical sequence should be:
Stage Width + Depth
↓
Deck Matrix
↓
Required Platform Height
↓
Vertical Support Configuration
↓
Access Configuration
↓
Final Component Package
This is a useful principle for other Ringlock stage projects as well.

Ringlock Structure
11. Horizontal Grid and Deck Relationship
The stage surface consists of 35 panels, but the lower support system should not be thought of as 35 independent mini-stages.
Instead, the horizontal members connect the support positions into a continuous grid.
The supplied BOQ contains:
80 pcs × 8ft horizontal pipes
plus:
84 pcs × 4ft horizontal pipes.
Those horizontal members coordinate with the 4 × 8ft platform dimensions and connect the vertical support points.
So the structure can be visualized as two coordinated layers:
Upper Layer
5 × 7 modular deck matrix
Lower Layer
interconnected steel support grid
The two layers together create one complete temporary platform.
12. Wooden Stage Surface
The source describes the stage topping as:
wooden
and the stair topping as:
wooden topping.
The source does not confirm:
plywood thickness;
anti-slip coating specification;
timber grade;
waterproofing specification;
fire rating;
allowable panel load.
Those specifications should therefore not be imported from another DragonStage product merely because similar stage panels may use plywood.
For this page, the accurate description is simply:
4 × 8ft wooden-topped stage panel.
13. Dual Stair Access
Two stairs are included in the confirmed configuration.
Each has:
5 steps.
The stairs provide access between the ground and elevated platform, but there is an important configuration issue:
the same five-step stair arrangement should not automatically be assumed suitable for every possible platform height from 0.4m to 2m.
The original page confirms the stair quantity and step count but does not provide enough detail to establish how stair geometry changes across all five stage-height options.
Therefore, for a new project:
platform height and stair configuration should be confirmed together.
14. Platform and Access Must Be Considered Together
Changing the platform height changes more than the steel framework underneath.
It also changes the vertical distance people need to travel.
That means:
Platform Height
↓
Access Requirement
↓
Stair Geometry / Step Arrangement
The original product includes two stairs, but a customized project may require a different:
stair quantity;
stair position;
stair width;
step configuration;
access direction;
edge-protection arrangement.
These should be confirmed before the final structural proposal.
15. Assembly Logic
At structural-breakdown level, the stage can be understood through the following practical sequence.
Step 1 — Establish the Stage Footprint
Set out the approximately:
12.2 × 8.54m
platform area.
Step 2 — Establish the Support Grid
Position the adjustable bases according to the required modular layout.
Step 3 — Install Vertical Supports
Connect the Ringlock pillars / vertical members to establish the required platform level.
Step 4 — Connect Horizontal Members
Use the 4ft and 8ft horizontal pipes to create the supporting grid.
Step 5 — Install Upper Support Interfaces
Fit the required forks and clamps.
Step 6 — Install the 4x8ft Stage Panels
Arrange:
5 × 7 panels
to form the complete stage surface.
Step 7 — Install Stage Access
Connect the two stair units according to the intended circulation arrangement.
Step 8 — Complete Project-Specific Edge and Access Requirements
Any required guardrails, edge protection or additional access elements should follow the actual project configuration.
This sequence explains the modular system logic. It is not a complete engineered erection procedure.
16. Confirmed BOQ
The source provides the following component list:
Component
Specification

Stage Topping / Deck

This BOQ is particularly useful because the component dimensions reveal the modular relationship between the 4 × 8ft deck surface and the 4ft / 8ft lower support grid.
17. Suitable Applications
This type of modular elevated platform can serve as a structural starting point for temporary applications such as:
concert stages;
festival stages;
ceremony platforms;
outdoor performance stages;
temporary event platforms;
production platforms;
elevated presentation areas.
The original product presents it as an event stage system.
Actual use conditions, loading, access and environmental requirements still need to be confirmed for each project.
18. Customization Variables
The 12.2 × 8.54m configuration should be treated as a reference structure, not a universal BOQ.
Variable
What It May Change
Stage Width
Deck matrix and support grid
Stage Depth
Deck matrix and support grid
Platform Height
Vertical supports and adjustment system
Deck Module
Horizontal support spacing

Stair Geometry
Platform access
Guardrails

Existing Ringlock Equipment
Compatibility and final BOQ
Site Surface
Base/support arrangement
Roof Integration
Overall structural proposal
LED / Sound Equipment
Additional support requirements
The most important lesson from this product is:
Do not finalize the BOQ from width and depth alone. Confirm height and access at the same time.
19. Existing Ringlock Equipment and Compatibility
Customers who already own Ringlock equipment may want to reuse part of their inventory.
That can be worth checking, but compatibility should not be assumed simply because both systems are called “Ringlock.”
Before reuse, confirm:
vertical tube diameter;
rosette/disc geometry;
ledger head and wedge connection;
ledger lengths;
vertical-member lengths;
adjustable-base dimensions;
fork/interface dimensions;
photographs of existing components;
existing BOQ or drawings.
If these dimensions do not match, a component that looks similar may still fail to integrate correctly.
20. Why This Is a Stage & Platform Structure
The original DragonTruss page calls the product:
Steel Scaffolding Ringlock Truss Stage.
For DragonStructure classification, however, the physical function is more important than the historical product name.
The complete system primarily exists to create:
an elevated temporary stage platform.
Therefore its primary classification is:
Ringlock Structure → Stage & Platform Structure
rather than Roof Structure, Access Structure or Hybrid Structure.
The steel scaffold is the supporting system.
The stage platform is the overall function.
That distinction follows the DragonStructure rule that classification should prioritize what the complete structure is designed to do.
21. Comparison with a Deck-on-Legs Portable Stage
A simple portable stage may use:
Deck
↓
Individual Legs / Folding Riser
With this Ringlock configuration, the relationship is more like:
4 × 8ft Deck
↓
Fork / Clamp Interface
↓
Horizontal Steel Grid
↓
Ringlock Vertical Supports
↓
Adjustable Bases
The result may look like the same thing from above—a flat stage—but the supporting logic underneath is different.
This distinction becomes increasingly important when platform size and height increase.

Ringlock Structure
These links extend the reader from this specific 12.2 × 8.54m configuration toward the broader structural system rather than simply sending them to unrelated products.
24. Engineering / Verification Boundary
The supplied product page confirms:
12.2 × 8.54m overall stage size;
35 × 4 × 8ft wooden-topped stage panels;
five supplied platform-height ranges;
48 LR01 pillar/inner-tube components;
80 × 8ft horizontal pipes;
84 × 4ft horizontal pipes;
48 forks;
40 clamps;
48 adjustable bases;
two 5-step stairs;
packing weight and volume for the five height configurations.
The supplied material does not provide verified engineering evidence for:
allowable stage load;
concentrated load;
uniformly distributed load;
lateral load;
wind resistance;
allowable height for a specific loading condition;
maximum adjustable-base extension;
ground-bearing requirement;
ballast or anchoring;
safety factors;
certification;
local-code compliance;
engineering approval.
These should not be inferred from the component quantities or from the fact that the product has previously been supplied.
For an actual project, the final structure should be evaluated against:
stage dimensions + platform height + intended use + equipment/occupancy + access + site conditions + environmental conditions + applicable local requirements.
