Top company. All structural work undertaken. Quality management.


Macalloy Ltd

Macalloy offer unrivalled customer service, dealing with our very specific requirements as a University! The products are very consistent in quality and can be relied on without doubt.


Macalloy Ltd

As a relatively small domestic customer for decorative, structural-tensioning components, I was pleasantly surprised at the seamless level of service provided from enquiry through to delivery, on the two occasions that I’ve made purchases. The provision of test certificates at no extra cost was unexpected and helped hugely with Building Control.
