Our MAIN PRODUCTS   Hollow Sections (ERW, CDW & Seamless)
 
The use of steel tubular sections provides for strong, light and profitable structures and as a result offer a host of possibilities in terms of application (expressive capacity). The use of these products also facilitates designs with a greater aesthetic appeal.
