Steel Grating Division Supplies Galvanised Walkway Grating in Q235, Q345 and S275 to 17 Standard Profiles

Rigid Grating Beside Flexible Mesh

Not every opening can be closed with cable netting. Walkways, plant platforms, drainage covers and industrial flooring need a rigid, load-rated surface, and Anping Yuhan supplies seventeen steel grating specifications to cover those duties. The range runs from lightweight expanded metal walkway panels to heavy galvanised bar grating in Q235, Q345 and S275 grades.

Standard Grating Profiles

Load and Specification Guidance

Bearing bar depth, bar pitch and cross bar spacing determine load capacity. For a pedestrian walkway at 5 kN per square metre, a 25mm by 3mm bearing bar at 30mm pitch with 100mm cross bar spacing is a typical starting point; vehicle access or heavy plant loading requires deeper bars or reduced span. Serrated bearing bars should be specified for any outdoor access route, ramp or stair tread where wet conditions are expected.

Hot Dip Galvanising and Finish

All carbon steel grating is hot dip galvanised to a coating weight suitable for exterior service, giving a zinc layer that resists atmospheric corrosion for decades in most environments. Cut edges and weld points are re-sealed after fabrication. For coastal or chemical exposure, aluminium grating or additional coating should be considered, since zinc consumption accelerates sharply with chloride contact.

Fixing and Safety Details

• Grating clips, saddle clamps and bolted fixings supplied to match bearer steel
• Toe boards and handrail posts available for platform edges
• Panels cut to size with banded edges to preserve rigidity after cutting
• Anti-slip serration and checker plate nosing on request

Supply

Seventeen steel grating profiles, in carbon steel hot dip galvanised, aluminium and expanded metal variants, are available for export from Anping Yuhan Metal Wire Mesh Co., Ltd. Drawings showing span, load and bearer layout allow the engineering team to confirm the correct profile before order. Enquiries via stainlesssteel-ropemesh.com.

Specifying Grating for a Project

Three inputs are enough for a firm quotation: the clear span between supports, the distributed load or vehicle class, and the required surface finish. From those, the engineering team selects bearing bar depth, pitch and cross bar spacing, then issues a panel schedule with cut sizes, banding and fixing quantities so site work is straightforward.
