Perfect Commercial and Residential Steel Sections


Main stream house building - 30% faster, 30% cheaper and 30% better than traditional build


HadFrame light gauge steel system is supplied and installed by Hadham Construction Ltd. It is computer designed 1.2mm to 2mm galvanised ‘C’ section steels, which is designed as a composite ‘honeycomb’ structure and manufactured on computer controlled linear presses. If the drawing is correct then the manufactured structure will be correct, as it is exactly as the drawing.


HadFrame uses a combination of Hot Rolled Steel and Cold Rolled Steel to design, manufacture and install interesting and unusual styles of houses. The honeycomb, computer designed structure is extremely strong and repeatable, making it cost effective for multiple units and sufficiently flexible to accommodate even the most challenging architectural requirements.


The ‘C’ sections are rolled, chamfered, swaged, punched and dimpled in the linear presses before being guillotined in the press to the exact length required by the drawing. This computer control ensures every single item is exactly as per the drawing. The items are then pre assembled at the factory into frames, labelled, flat packed and delivered to site, as assembled steel frames.


The footings are usually an RC raft with a stepped toe detail matching the Standard Details. The pre assembled steel frames are positioned on the edge of the RC raft after the application of the DPM, aligned and secured. The ground floor cassettes which are pre boarded are craned into position creating the first floor and removing the requirement for internal scaffolding. Stairs are fitted during the build providing access to each level.


All structural calculations are provided by Hadham Construction Ltd along with a detailed Installation Manual and Handover to Following Trades Manual. A full installation service is provided from steel only to full turnkey completion, depending on client requirements. A full training service is also provided to the HadFrame accredited system to assist with re-training of clients own staff and sub contractors.


The build continues for each level up to eaves. The pre boarded roof cassettes are then craned on and secured to the walls and flashings.


Composite panel or traditional roofs are fitted, external doors and windows, external insulation and brick slip, render, brick effect render or composite panel wall cladding is fitted to complete the external envelope.


The structural openings are all exactly as per the drawings and so all external doors and windows can be ordered from the plans without having to wait to site measure due to inaccuracy during build.


All service holes are pre stamped and lined removing the need for drilling holes in studs.


The windows, doors and roof are therefore ready to be fitted as the steal is finished.


Two skins of plasterboard are fitted to the inside, the steel profiles full filled with mineral wool and CP board fitted to the outside of the steel.


There is no cavity.


The solid insulation is fixed direct to the CP board, and brick slip / render etc to the external of the insulation.


The external doors and windows are sealed and the super structure is complete. Facias, sofits etc by Hadham or others as required.


The external finish can be made to suit all environments from modern to traditional. 0.14 - 0.15 U value as standard with no extra cost. A steel frame for a 3 bed house is erected in five days and the external envelope can be complete in three weeks. 4 weeks from DPC to wind and waterproof external envelope with floors, internal walls and stairs.
