Jan. 02, 2026 Supplying 1200 Sets of Edge Protection Fences to a U.S. Company
Location: Houston, United States
Date: October 15, 2025
Product: Edge Protection Fences
Application: Construction Site Fall Protection & High-Risk Area Safety Isolation
I. Project Overview
A leading U.S. construction firm is executing a large-scale commercial complex project in Houston, spanning 380,000 square meters with high-rise office buildings, premium shopping centers, and supporting facilities. The project involves multiple high-risk work zones, including elevated working platforms (15-30 meters high), roof edges, scaffolding perimeters, and floor openings during the construction phase.
According to the U.S. Occupational Safety and Health Administration (OSHA) standards (1910.29 for guardrail systems and 1926.501 for fall protection), the client required edge protection solutions that combine robust safety performance, durability, rapid installation, and compliance with local regulatory requirements. After a three-month evaluation process involving technical demonstrations, sample testing, and on-site inspections, our edge protection fences stood out for their OSHA-compliant design, superior structural integrity, and long-term cost-effectiveness. The client ultimately placed an order for 1200 sets to safeguard the project’s construction safety and ensure uninterrupted progress.

Top/Mid Rails: 50mm×30mm×2.0mm rectangular steel tubes (mid rail centered between top rail and toeboard)
Mesh Details: 5mm×8mm double-strand steel wires; 50mm×200mm rectangular mesh (balances protection and visibility for on-site supervision)
Toeboard 2.5mm thick cold-rolled steel; 150mm vertical height (gap ≤ 6mm between toeboard and ground to prevent falling debris)
Surface Treatment
1. Primary anti-corrosion: Hot-dip galvanization (zinc layer thickness ≥ 120μm, conforming to ASTM A123 standards)
2. Secondary protection: Electrostatic powder coating (RAL 3000 red; customizable to RAL 1023 yellow/RAL 5010 blue)
3. Testing: Passed 2000-hour neutral salt spray test
Installation:
- Uprights: Flange-mounted (200mm×200mm×8mm steel base plate) with 3 M16 expansion bolts for concrete/steel surface fixation
- Panel Connections: Quick-locking 304 stainless steel buckles (tool-free, no on-site welding)
- Single panel weight: 18kg (easy for 2 workers to handle)
III. Quality Assurance
To ensure full compliance with OSHA standards and reliable performance in harsh construction environments, we implement a strict 12-point quality inspection process for each batch:
Verify raw material certifications (steel wires and tubes meet GB/T 3077-2015 and ASTM A36 standards)
Inspect mesh size accuracy (tolerance ±2mm) and welding firmness (each weld tensile strength ≥ 350N; no false welding)
Test top rail height (42 ± 3 inches above the working surface, aligning with OSHA 1910.29(b)(1))
Assess structural impact resistance (≥ 10kN horizontal load applied to top rail without permanent deformation)
Check toeboard installation tightness (gap ≤ 6mm; no warping or loose connections)
Validate coating thickness (powder coating ≥ 80μm; galvanized layer ≥ 120μm) via magnetic thickness gauge
Conduct cross-cut adhesion testing (ASTM D3359-09) to ensure coating adherence (no peeling)
Inspect surface smoothness (all edges deburred; top rail folded at 90° to eliminate sharp points)
Test locking buckle durability (500+ opening/closing cycles without failure)
Verify dimensional consistency (height/length tolerance ±5mm; upright spacing ±10mm)
Conduct load-bearing tests (200 pounds of upward/downward force on top rail, no deflection below 39 inches)
Review compliance documentation (OSHA certification No.: OSHA-2025-HOU-0876; material test reports)
IV. Execution Highlights
OSHA Full Compliance: Every design detail meets OSHA 1910.29 (guardrail systems) and 1926.501 (fall protection) standards. Third-party OSHA compliance certification ensures smooth customs clearance and on-site acceptance.
Enhanced Safety Design: Three-tier protection system (top rail + mid rail + toeboard) eliminates fall risks; double-strand mesh and reinforced frame resist up to 50kg impact from tools or materials.
Rapid Installation & Reusability: Modular design with quick-locking buckles allows single-panel installation in ≤ 5 minutes (2 workers) — 60% faster than traditional welded fences. Detachable structure enables repositioning and reuse across projects, reducing long-term costs by 30%.
Extreme Durability: Dual anti-corrosion treatment withstands harsh environments (temperature range: -20°C to 60°C; humidity, construction chemicals) with a service life of over 10 years.
Cost-Effectiveness: Lightweight design reduces transportation costs (20 sets per 40GP container); tool-free installation cuts labor expenses; reusability lowers total ownership costs.
V. Application Scenarios
High-rise construction: Floor edges, scaffolding perimeters, elevated working platforms
Roof construction: Roof edges, skylight openings, mechanical equipment installation zones
Infrastructure projects: Bridge construction zones, tunnel entrances, road maintenance barriers
Industrial facilities: Mezzanine edges, warehouse hazard zones, heavy equipment work areas
Public works: Municipal construction sites, park renovation high platforms, utility trench openings

VII. Results & Customer Feedback
“The 1200 sets of edge protection fences have been successfully installed across our construction site, and initial inspections confirm full compliance with OSHA standards. The rapid installation process minimized disruptions to our schedule, and the durable design has withstood heavy rain and temperature changes without any signs of corrosion or deformation. The on-site technical support was professional and responsive, addressing all our questions promptly. These fences not only enhance on-site safety but also reduce our long-term operational costs through reusability. We are highly satisfied with the product quality and service, and look forward to future cooperation on upcoming projects.”
