MCRMA produces a range of publications designed to educate specifiers and contractors alike on metal building envelope design, the systems available, their application, superior life expectancy and unrivalled value over other material alternatives.

The Guidance Documents below set out to answer some of the frequently asked questions relating to building envelope systems and their components. The documents cover a wide range of topics including  working at heights, CE marking, installation of purlins and side rails, CDM regulations and non-fragility.

The technical design guides are available primarily as a reference resource and will prove particularly useful to specifiers who need to check on metal building envelope specifications of the last 25 years.

MCRMA has published an Advice Note which summarises the main points of the recently announced amendments to Building Regulations and Approved Document B for England. The amendments relate to external wall constructions for relevant residential and institutional buildings.


All guidance documents are subject to regular review and updating. It is the reader’s responsibility to ensure that they are using the latest version of any given publication. Readers are also advised that the MCRMA web site is the definitive source of reference for guidance documents and external web sites which host MCRMA publications should be treated with caution.

Manufacturers are best placed to offer advice about their particular products and their published data should be closely adhered to; as any variation from their data during the design or construction process could result in the component or system failing prematurely or not complying with the guarantee or warranty conditions. Any uncertainty about the use or application of a product or system should be referred back to the manufacturer for detailed written advice.
