Stairs can be more than simply functional, they can also be an artform - not just around the home but also in the commercial setting.

Wallace Construction in Takanini wanted to add some pazazz to their entrance way so called Sheetmetals Ltd.  Our team discussed the materials available and settled on a cladding in natural black finish hot rolled mild steel with a wax finish.  A powder coated hand rail was added to match.  These materials were selected due to their functionality and practicality in the industrial setting - not just their looks!!

Hot rolling is a metalworking process that occurs above the recrystallization temperature of the material. After the grains deform during processing, they recrystallize, which maintains an equiaxed microstructure and prevents the metal from work hardening. The starting material is usually large pieces of metal, like semi-finished casting products, such as slabs, blooms, and billets. As the material is worked the temperature must be monitored to make sure it remains above the recrystallization temperature.

While the finished product is of good quality, the surface is covered in mill scale, which is an oxide that forms at high-temperatures. It is usually removed via pickling or the smooth clean surface process, which reveals a smooth surface.  Hot rolling is used mainly to produce sheet metal or simple cross sections. Other typical uses for hot rolled metal includes truck frames, automotive wheels, pipe and tubular, water heaters, agriculture equipment, strappings, stampings, compressor shells, railcar components, wheel rims, metal buildings, doors, shelving, discs, guard rails, automotive clutch plates.
