Security certified to LPCB 1175

Industrial doors are often the last line of defence for a sensitive asset. We’ve designed, tested and certified our range of security flood doors to ensure they provide industry-leading protection from flooding and intruder entry. 

Custom-designed for your project

Flood levels, sizes and door functions required vary greatly from project to project. Our design team engineers your needs; they can design doors to withstand up to a full-height head of water. Any flood door supplied by MM Engineering is sized and made precisely for your site, so you’re guaranteed flood defences that are right for you.

Superior locking mechanisms

Our security doors feature high-security locking mechanisms by Surelock McGill, industry leaders in locking and security, to ensure maximum safety for your assets.
