Configured for industrial projects
Built around your operating conditions.
Bearing and cross bars joined by forge welding at each crossing. The most common grating type for industrial platforms, walkways and trench covers.
- Dimensions, material and finish confirmed against drawings
- Engineering support for spans, loads, installation and standards
- Coordinated supply with frames, fixings and edge protection
Specifications
- Manufactured by electrical resistance (forge) welding — each bearing-bar/cross-bar intersection is fused into a rigid joint
- Bearing bars: 20 × 3 mm through 75 × 8 mm. Most common: 25 × 5, 32 × 5, 40 × 5 mm
- Spacing: 30 mm (most common), 34 mm, 40 mm. Cross bars at 50 mm or 100 mm pitch
- Surface: plain or serrated. Serrated adds slip resistance for wet and oily areas
- Material: carbon steel ASTM A36 / S275JR / SS400 hot-dip galvanized. Stainless 304/316L
- Panel sizes: up to 1000 × 6000 mm standard. Cut, notched and banded per drawing
- Standards: BS 4592, NAAMM MBG 531, YB/T 4001.1, EN ISO 14122, AS 1657
Common model designations
| Pitch / style | Typical bar size | Typical use |
