Importadora Monterrey SRL We provide steel solutions for civil construction, with excellent quality products, accompanied by a specialized technical advisory service in the hands of professionals in the field. Our steel has the backing of the world's No. 1 steel company, ArcerlorMittal. Our star product, corrugated steel or corrugated rod, is a type of laminated steel designed especially to build reinforced concrete structural elements. These are steel bars that have protrusions or corrugations that improve adhesion to the concrete, and have great ductility, which allows the bars to be cut and bent more easily. Among other products we have corrugated corrugated iron sheets, tile type and trapezoidal, with colors to choose from, nail factory, wheelbarrow factory, barbed wire, galvanized wire, PVC doors and windows, the BELGO PRONTO iron cutting and bending service, the entire range of the SOLDEXA welding line and the TAURO welding machines, as for new products we have the plastic separators of the COPLAS brand. The separator is a small piece whose very important mission is to place the steel of the reinforcement perfectly housed within the concrete until it sets.Geo: Bolivia - Leak size: 34.6 GB Archive - Contains: Files
