Metal joinery businesses make and install metal components used in buildings and other settings. Work commonly includes doors, window frames, screens, partitions, gates, railings, handrails, balustrades, security grilles and other architectural metalwork. Depending on the project, items may be made from steel, stainless steel or aluminium, in standard sizes or to measured specifications. Services can include taking dimensions, preparing drawings, cutting and shaping metal, welding and assembling parts, and applying finishes such as paint, powder coating or galvanising. Businesses may supply components for new buildings, refurbishments or replacement work, and some also fit, adjust or repair existing metalwork. Customers can include householders, builders, property managers, architects and commercial organisations. The scope varies between businesses: some specialise in doors and windows, while others undertake decorative work, security fittings or larger fabricated assemblies.
