Load bar's centre distance 60mm, cross bar's centre distance 100mm; Load bar's centre distance 60mm, cross bar's centre distance 50mm.
Series 3 grating is mainly used in the mining industry as it minimises the build-up of spillages on the flooring. The openings let small matter fall through while larger matter is caught on the grating. Series 3 is a very lightweight design and is not recommended for high-impact load.

Features: High strength, light structure; beautiful appearance, durable; ventilation, lighting, heat dissipation, explosionproof, corrosion resistance, good performance of skidproof.

Uses: Steel grating are widely used as platform, pavement, trestle, drain cover, manhole cover, ladder, fencing in field of petrochemical engineering, power plant, water plant, sewage treatment plant, municipal engineering, environmental engineering etc.
