|
Steel has come a long way since its early use for corrugated roofing. It has evolved into pre-finished steel where a number of paint layers are applied in an automated and carefully controlled manufacturing process. From here the pre-finished steel is profiled into cladding and delivered to a construction site as part of a wall or roof system. Pre-finished steel is enormously versatile and offers the building designer a material that is high quality, cost effective, robust and visually strong. Here we explore what pre-finished steel is, its application and benefits as a material for building envelopes and the way in which it is manufactured and processed further. | |
| |  Pre-finished steel products used within the construction industry are made up of a series of layers, each with a particular function, synergistically applied to provide the functional and aesthetic performance required.
|
|
| |  Pre-finished steel is extensively used for the building envelope. Manufacturing under factory controlled conditions to exacting standards provides high quality and cost effective pre-finished steel products which can be processed further into finished systems such as composite panels, roof sheeting and façades.
|
|
| |  The choice of pre-finished steel product is a key decision in the overall performance of a building system. Pre-finished steel is manufactured by a coil coater and then sold to customers such as panel and profile manufacturers who fabricate the coil into the final cladding system.
|
|
| |  The coating process can be considered within three zones: entry, process and exit. Pre-finished steel is manufactured within a continuous process which guarantees high quality standards through controlling the coating thickness, colour, gloss, adhesion and corrosion resistance.
|
|
| |  Pre-finished steel is used in a wide range of construction applications, both exterior and interior. These include roof and wall cladding systems, garage doors, roller shutter systems, internal partitioning, ceiling systems and doors. Pre-finished steel provides a key function in the appearance and performance of the finished system and building.

|
| |  Until pre-finished steel coating technology emerged in the mid 1960s, the most common material used for roof and wall applications was asbestos cement.
