stretcher bars in Aluminium


ALUSTRETCH®™ is a maker of premium quality aluminium stretcher bars and canvases for artists, galleries and museums. The stretcher bars are made to suit the needs of professional artists and have a finely honed and easy-to-use design.

They are made to order at any size and are available either in kit form, made up, or stretched with a wide variety of surfaces and preparations.                                                                     

They are easy to assemble/disassemble, are lightweight and will never warp or twist, even in the most trying conditions. The stretchers have a wooden inlay for easy fastening, and a simple tension system for tensioning canvas. 

Designed and made within the EU using predominantly recycled aluminium and sustainably sourced poplar plywoods, we aim to minimise our impact on the environment.

Alustretch UK is artist owned and operated.

ALUSTRETCH®™ stretcher bars are designed to provide a stable painting substrate in all conditions and with all types of canvas. Built around a T6 aluminium profile with an optimised wall thickness, they provide the necessary strength and stiffness that makes preparing large canvases trouble-free and lighter than you might think. We are confident in the ability of the design to hold canvas tension for far longer than with conventional stretchers. At the heart of the design is the tension system, made from die-cast zinc parts and held in place with small steel grub screws. Die-cast zinc parts are used for accuracy of manufacture strength and reliability. It may seem like overkill to use such an exacting processes and materials, but it is all designed to create the most stable and long-lasting painting surface that we can. Using aluminium's inherant strength and rigidity, canvases can be held under much higher tensions. This is particularly useful when working with raw linen and also gives the opportunity to work with very large sizes, where a traditional wooden stretcher would struggle to cope.

Using only the highest quality primers & gesso’s from Lascaux, we can prepare a wide variety of specialist artists surfaces, from hand priming and tinted gesso finishes, to the traditional application of rabbit skin glue on to linen or canvas. Where size is critical, we hand prepare extra large canvas up to 4.2m in width. We supply high quality linens from Claessens in Belgium as well as technical canvases (polyesters), cotton duck and projection materials from Fredrix and Harkness accordingly.
