Steel Grating
Standards.
Multi-stage inspection verifies raw material chemistry, welding quality, panel dimensions, load capacity and hot-dip galvanizing thickness for every grating order.
Compliance documents
ISO 9001:2015
Certified Quality Management System ensuring consistent product quality, traceability, and continuous improvement across all manufacturing lines.
CE Conformity
Full compliance with European health, safety, and environmental protection legislation for construction products and steel structures.
ASTM F1267 Compliance
100% material traceability. Every shipment is accompanied by a Mill Test Certificate detailing chemical composition and mechanical properties.
Testing Procedures
Multi-Stage Quality Control
Raw Material Spectrometer Testing
Verifying the chemical composition of incoming steel to ensure it meets structural grade requirements (e.g., Q235B, ASTM A36).
Dimensional & Visual Inspection
Checking tolerances for length, width, squareness, and cross-bar alignment before and after welding.
Load Verification Testing
Applying hydraulic pressure to sample panels to verify deflection limits and ultimate load capacities.
Galvanizing Thickness Check
Using magnetic thickness gauges to ensure zinc coating meets or exceeds ASTM A123 / EN ISO 1461 standards.
