Allerton Steel is currently fabricating a footbridge for installation in the West Midlands. Bridge span is 62m and weight 170t.
The picture shows the central arch section which weighs 25t and is 26m long x 4m wide x 3.4m high. It is fabricated from dia 660 x 25mm wall tube from S355J2H steel.
The largest deck section was 31t and is 25.3m long x 5.7m wide, with two further deck sections completing the bridge deck.
Once on site in the West Midlands, the three deck sections, central arch and four lower arch sections, will be welded together ready for installation by a 1250t crane lifting 170t structure, with super lift, at a 35m radius during a 24hr road closure.
In line with current bridge standards this project is manufactured and tested to BS EN 1090-2 Exc 3. The whole structure is protected with Highways paint system Type II.
Operating from modern workshops and office facilities on two sites, with over 6,950 sq m (75,000 sq ft) capacity. The workshops offer a lift capacity up to 60 tonnes and are equipped with modern plant and machinery including semi-automatic welding, CNC operated profile, saw, drilling and milling machines. Additionally, we have a 3D modelling and surveying system to assist with complex fabrications and inspection.
