Metal Roof and Cladding 0.43mm 980mm
Metal cladding systems provide an efficient, attractive and reliable solution to the building envelope needs of single storey buildings. Over the years, these systems have evolved from the single skin metal cladding often associated with agricultural buildings to highly developed systems used in industrial, retail and leisure applications. However, as with all construction components, the ability of the building envelope to satisfy its functional requirements is dependent on its correct specification and installation and, equally as important, on its interaction with the other elements of the building envelope and structure.
This article explains metal envelope systems and how they are designed, specified and procured.
Insulated roof and wall cladding panels consist of a rigid layer of insulation sandwiched between two metal skins, as shown below. The result is a strong, stiff, lightweight panel with good spanning capabilities due to composite action in bending. The panels span between cold formed purlins or side rails, which in turn span between the primary frame members. However, where the secondary steelwork is not needed for restraint purposes, it is quite common for composite wall cladding panels to span directly between the primary framing.
| Advantages |
| Corrosion Protection : Superior Coating Quality provides excellent corrosion protection in various climatic conditions, hence enhances life. |
| Additional Protection : It protects the sheet from transit and storage damage and lubricates the sheet surface during forming. This gives longer life & retention of appearance. |
| Formability & Aesthetics: Easy formability and bending property opens new horizons to the architect's creativity. The wide range of colors provides options to the architect to customize requirements. |
| Convenience: They are Economical as they require lighter supporting structure and also reduce transportation costs. And they are virtually maintenance free. |
| Consistent Quality: Ensures excellent performance in all weather conditions and hence enjoys trust & confidence of millions. |
| Thermal efficiency: Roofing Sheets & Cladding results in less heat radiation compared to other commonly used roofing materials. Colouron when combined with insulation makes a cost effective, energy efficient roofing system. |
| Environment friendly: Colouron galvanised steel has a long life and if eventually replaced are recyclable without losing quality. The paint used to coat the base metal is also toxic free. |
