Our company engineers and builds simple and complex structures with modular aluminium profiles (some pictures of our products and some of the realisations can be found in the attachments).
Examples are simple machine frames, conveyor belts, guardings, linear systems, workbenches etc.
Surf to http://www.item24us.com, This should give you a pretty good idea of the product itself.
We sell these structures to machine builders, industrial automation companies, automotive companies, pharmaceutical and biotech companies and industrial manufacturing in general.
In the past, engineers had to weld steel in order to make customised constructions. By using a modular building kit based on aluminium profiles that can be cut, drilled or abraded, your construction will be cheaper, lighter, nicer and adjustable.
