  • 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.

  • The support from Macalloy is spot-on every time. The Sales team at Macalloy are quick, polite, and efficient, and every time we come to install the tension bars they fit first time. Great service- great product.

  • The Macalloy rods look really great, personally it’s my first time using them (though others in my office have spec'd them before) and it has all come together beautifully!

  • Macalloy have provided us with several varieties of their Tension Rods for a number of projects over the last 18 months or so, including being an integral supplier of materials for the new flagship Ikea Store in Greenwich. Macalloy have supplied a quality product matched by quality service.

  • Plas-Tal has used Macalloy as our rod supplier over the past few years on a specific project of ours. We find the service and items provided by Macalloy to be professional & accurate and would definitely use them again on future projects. To my surprise, everything ran pretty smoothly based on ordering goods from overseas.
