Steel railing BRIDGE

tubular systemmodular

Description
The Bridge guardrail is designed to provide mechanical strength, durability and ease of installation. It is particularly suitable for protecting pedestrian routes in road, urban and extra-urban environments. It is sized to withstand a linear horizontal service load up to 150 daN/m (1.5 kN/m).

Specification
The Bridge guardrail is a modular system composed of posts, handrail and infill panels in welded steel grating. The upper handrail is a square steel tube 40×40×3 mm, connected to the posts by specific fixing plates. The vertical posts are made of rectangular tube 80×40×4 mm and include a base plate with four holes for fastening to the supporting structure. The infill is formed by Svevia welded grating panels with 62×132 mm mesh, complete with upper and lower frames in 25×4 mm flat steel. The clear distance between posts is 2,014 mm.

Characteristics

• Designed for ordinary pedestrian use
• Verified for a horizontal load of 150 daN/m (1.5 kN/m) applied on the handrail surface
• Elements arranged to discourage climbing according to UNI 10809
• Impermeable to a sphere of 100 mm diameter according to DM 238/1989
