Door Leaves Manufactured from 1.2, 1.6 or 2.0 Zintec steel, double skinned with interlocking seams reinforced vertically with interlocking channels and horizontally with tubes to prevent twisting. Spaces are filled with dense Rockwool or honeycomb, which is still as strong and rigid as a rockwool filled leaf but is very much lighter. This is a better option if powder coating is required. Steel Door Frames Manufactured from 1.6 or 2.0mm Zintec Steel, frames are formed to either a single or double rebate. Choosing a Steel Door An opening outward lipped door with a cill and weather canopy is the best option. The lip protects the latches and bolts. It is harder to pull a door off than to ram it inward. It is much better for weather proofing and it saves internal spaces. Escape Steel Door If regulations require a minimum clearway, add 126mm to the width and 63mm (no cill) to the height to arrive at the structural opening required. Door Handing The handing is defined by viewing the door from the pull side. If the hinges are on the right side it is a right hand door. Double The handing is based on the first opening leaf. Viewing from the pull side, if the hinges of the primary leaf are on the left, then the door is defined as a left hand door Steel Door Furniture A full range of locks, panic furniture, door closers, door stays, monkey tail bolts, shoot bolts, hinges and letter boxes by all the major manufacturers are available.
