EN124
Manhole covers should meet the requirements of the European Standard BS EN124:1994. This applies to all situations, road and off-road and all materials. Covers fitted in footpaths and other areas which may have occasional vehicle loads must be third party certified to Class B125 of EN124.
Manual Handling
Salmor covers are designed with manual handling requirements in mind and feature slide out covers with tapered sides. These features allow covers to be safely removed by one person. Cover sizes are designed to ensure safe lifting weights and multi-cover sets include removable cross members.
BT Approved
BT badged units are manufactured in accordance with BT specification LN593 and are kitemarked to Class B125 of EN124:1994. The covers are 75mm deep as standard and are fabricated in 6mm steel. BT units also incorporate a slide-out feature for single person operation. Specifiers should take care to ensure that approved suppliers are properly specified on bills of quantity.
Infill Materials
Because the covers are tested unfilled, they can be filled with any chosen landscaping material including paving bricks, cobbles, natural stone slabs, tactile paving, tarmac or even grass.
Quality
Salmor Industries operates a quality management system which is accredited by BSI to BS EN ISO 9002. All components are hot dip galvanised to BS EN 1461:1999 after manufacture to ensure a minimum life of 40 years.
