Bespoke Constructions

We design custom-built solutions for projects requiring special, multi-performance rated hinged, sliding and folding doors in personnel and oversize configurations. At our Special Projects and Product Development base we combine structural and blast engineering skills with many years of cumulative experience in the steel door industry to provide design support for architects and consulting engineers, supported by post contract award, project-specific assessments or tests.

Product Specification Advice Service

We provide a technical advice service for bespoke, project-specific doors at the design and specification stages.

Based on many years of experience in the construction of high integrity, purpose-made doors and wall systems, and we are available to provide advice on the construction of special-purpose doors and the feasibility of achieving exceptional primary, and multi-performance ratings, backed by expert opinion of the likelihood of securing test house assessments post contract award.

This service extends to advice on the structural design of peripheral door support structures.
