Ductile Iron Covers and Frames Range
New Ductile Iron Covers and Frames range | |
Integrated Ducting Systems (IDS) have recently added a new range of ductile iron covers and frames to complement their existing range of composite covers and ductile Iron frames, for use with their recycled plastic access chamber system. Ductile iron has historically been used in the manufacture of covers and frames used for highways and pavement applications. The new product range consists of covers and frames to B125 and C250 loadings. The B125 covers and frames are medium duty to BS EN124 standard and are designed to withstand 12.5 tonne loadings. The C250 covers and frames are heavy duty to BS EN124 standard and are designed for slow moving heavy traffic up to 25 tonne loadings. | ![]() |
Features & Benefits
- Kitemarked quality assured products
- Ductile iron provides an improved weight to strength ratio
- Black coated finish
- Badged IDS traffic signals/street lighting
For technical drawings and further information on the B125 and C250 product ranges visit our download pages or contact us for expert advice. The new ductile iron covers and frames are now available for delivery nationwide throughout the UK & Ireland via our network of Burdens branches . Please contact us for export enquiries.

Ductile Iron Frame Specification Clause
Frames shall be IDS system manufactured under ISO 9002 approval and shall meet the load requirements of B125. Manufactured from ductile iron and installed in conjunction with IDS installation instructions. The frame, which has a locking facility, locates inside the chamber and can be adjusted for both height and tilt to finished levels.
Ductile Iron Universal Frame - DUNF
A new development by IDS features the introduction of ductile iron frames to our range. Ductile iron is widely used within civil engineering and provides a strong, robust and aesthetically pleasing finish to the chambers. An important feature of this frame is the flange which is specifically engineered to accommodate better adhesion and keying in qualities to the concrete surround. All frames are complete with a locking facility and are clearly marked with the component reference for easy specification and ordering.
