Example Technical Specifications

Design

Designed in accordance with "European recommendations for the stressed skin design of steel buildings" and relevant British Standards.

External Cladding

Cladding choices are available to suit client requirements. For economy we usually use HP200 Plastisol coated profiled steel external sheeting. Other options include semi flat sandwich panels and/or parapet walls to conceal the roof line. All cladding material is manufactured from "Galvatite", a hot dipped zinc coated steel. The substrate is of grade Fe E280G commercial quality mild steel with a minimum yield stress of 280 N/mm2 . Galvanised coating is to a minimum thickness of 275 g/m2 with a conventional spangle finish. The steel substrate fully complies with the provisions of British Standard BSEN 10147: 1992.All steel is profile rolled to comply with the provisions of BS 5427: 1976 in respect of materials, design, handling, working, performance and storage.
