Product Specification & Technical Detail: Heavy-Duty Industrial Steel Trestle System
Technical Specifications
To ensure precise engineering alignment, the following specifications define the standard build of our steel trestles:
Material Composition: High-grade S235/S355 Carbon Steel.
Surface Treatment: Hot-Dip Galvanized (HDG) to BS EN ISO 1461 standards for superior corrosion resistance, or high-durability Powder Coating.
Load Capacity: Tested for Safe Working Loads (SWL) up to 450kg per pair (depending on height extension).
Height Adjustability: Multi-stage locking pin system with a typical range of 0.8m to 1.4m (Custom ranges available).
Top Rail Width: Standard 0.9m to 1.1m to accommodate up to 4 standard scaffold boards side-by-side.
Locking Mechanism: High-shear strength steel captive pins with galvanized retaining chains.
Structural Design Features
A. Reinforced A-Frame Geometry
The trestle utilizes a wide-base A-frame architecture to distribute vertical loads efficiently. The diagonal bracing is precision-welded to the vertical uprights, minimizing lateral sway and ensuring structural integrity even at maximum height extension.
B. Telescopic Vertical Adjustment
The inner tubes feature precision-punched holes at regular intervals. The telescopic design allows for micro-adjustments on uneven terrain, ensuring a perfectly level working platform. The captive pin system prevents component loss and ensures a secondary safety lock.
C. Flat-Pack & Foldable Design
For logistics efficiency and warehouse space management, the trestle is designed with a folding pivot mechanism.
Transportation: Units can be stacked horizontally, significantly reducing shipping volumes for 40'HQ containers.
Deployment: Rapid setup and strike-down times without the need for specialized tools.
D. Enhanced Footplate Stability
Each leg is terminated with a circular or square steel footplate. This increases the surface area contact with the ground, preventing the trestle from sinking into softer substrates and providing a secure anchor point.
System Integration: Staging & Walkways
Our trestles are designed as a modular system. As seen in the operational configurations, multiple trestle units can be linked using Aluminum Staging Planks or Catwalks to create an extended, continuous working walkway.
End-Stop Brackets: The top rail includes integrated vertical stops to prevent lateral movement of the staging boards.
Tandem Configuration: Ideal for bricklaying, plastering, and ceiling installations where a wide, stable footprint is required for both the operator and materials.
Manufacturing Excellence & Quality Control
As a dedicated manufacturer, our production process adheres to strict industrial protocols:
Raw Material Inspection: All steel batches undergo tensile strength verification.
Robotic Welding: Critical joints are welded using automated systems to ensure deep penetration and consistent bead quality, eliminating human error.
Load Testing: Batch samples are subjected to static load tests to verify the factor of safety (FOS).
Galvanization Integrity: We ensure a minimum zinc coating thickness of 65-85 microns for HDG products to withstand coastal and high-humidity environments.
Safety & Compliance
Standard Compliance: Designed in accordance with BS 1139 and EN 12811-1 standards for temporary works equipment.
Safety Instruction: Always ensure the trestles are placed on a firm, level base. Do not exceed the rated Safe Working Load. Ensure all locking pins are fully engaged before ascending the platform.
Global Export & Logistics
We specialize in B2B supply chains, providing optimized packaging solutions for international distributors:
Custom Branding: OEM services for embossed logos or custom powder coating colors.
Documentation: Full provision of MTC (Mill Test Certificates), Packing Lists, and Proforma Invoices compliant with international trade regulations.
Capacity: High-volume output capability to meet large-scale infrastructure project timelines.
Why Choose Our Trestle System?
Our focus is on Engineering Reliability. We provide a product that prioritizes structural thickness and weld integrity over cost-cutting measures. This ensures a longer service life and a lower total cost of ownership for rental companies and construction firms.
