The global construction industry is witnessing unprecedented growth, driven by urbanization and infrastructure modernization. As a professional leader in formwork and scaffolding systems, Lianggong Formwork Company stands at the forefront of this evolution. With certifications including EN 1090-2, ISO 3834, and ISO 9001, alongside a team of internationally certified welders and engineers, we deliver trench boxes engineered to exceed global safety benchmarks.

The Rising Demand for Standard-Compliant Trench Boxes

Trench boxes are critical for safeguarding workers during underground pipeline installations, cable laying, and excavation projects. However, not all trench boxes are created equal. Variations in international standards—such as U.S. OSHA regulations, European EN 1090 specifications, and Australian AS/NZS 5131 codes—create complex compliance challenges.

Key Material Comparison

Property	S355B Steel (Ours)	Q235 Steel (Standard)	Improvement
Yield Strength (MPa)	355	235	+51%
Tensile Strength (MPa)	490-630	370-500	+25%
Corrosion Resistance	25+ years*	10-15 years	+67%
*Based on salt spray testing (ASTM B117) with epoxy-galvanized coating.

Our trench boxes are crafted from S355B structural steel, a high-strength material validated by third-party labs to meet or exceed global standards.

Solving Hidden Pain Points in Trench Box Applications

1. Soil-Specific Load Capacity

Our modular systems adapt to soil classifications defined by OSHA and Eurocode 7:

Trench Depth (m)	Soil Type	Max. Load (kN/m²)	Lianggong Model
3.0	Type A (Stable)	45	TBX-300A
5.5	Type B (Medium)	72	TBX-550M
8.0	Type C (Unstable)	108	TBX-800C

2. Global Certification Coverage

Region	Standard	Compliance Proof
North America	OSHA 29 CFR 1926	AWS D1.1 Welding Cert + Load Test Reports
Europe	EN 1090-2	CPR Certification + Material Traceability
Middle East	SASO-Certified	Third-Party Sand Erosion Testing (ASTM G65)

Why Lianggong’s Trench Boxes Stand Apart

Customization Range

Parameter	Specification
Panel Height	1.2m – 8.0m (adjustable in 0.3m increments)
Wall Thickness	8mm – 16mm (S355B steel)
Connection System	Boltless Interlock (Patented Design)
Lead Time	15-25 days (50% faster than industry avg)

Durability Testing Results

Test	Standard	Result
Cyclic Loading	EN 12812	10,000 cycles @ 150% design load
Weld Integrity	ISO 5817-B	0 defects (100% X-ray passed)
Coating Adhesion	ASTM D3359	5B (highest rating)

Global Standards, Local Expertise

Our regionalized engineering ensures compliance without compromising efficiency:

· U.S. Projects: Pre-calibrated for OSHA Appendix C soil pressure tables.

· EU Projects: Full EN 1090-2 Execution Class 2 documentation.

· Tropical Zones: Anti-microbial coatings to prevent biofilm buildup (tested to ISO 22196).

Conclusion: Partnering for Safer Excavations

Lianggong’s trench boxes merge certified safety with unmatched adaptability, backed by empirical data from 1,200+ global projects. From material science to onsite support, we eliminate guesswork in trench shielding.
