FIRAT reinforcement steel are manufactured in hot dipped galvanized class as per TSE 822 with zero defect and as integrated with our profiles thanks to computer-aided control system throughout all production stages including cutting, bending and packaging in accordance with FePO2g quality and DIN standards applicable for profile operations in accordance with TSE EN 10142. Hot dipped galvanized sheets are subject to zinc coating test before production. Hot dipped galvanized sheet has long service life and high resistance to corrosion. Its zinc coating does not come off even when shaped by bending. It is resistanct against fire and all kinds of external effects. Loss of coating thickness is minimum under normal air conditions. Quality control tests are continuously performed in our advanced laboratories throughout all stages like raw material, before, during and after production. Forming skeleton of FIRAT PVC window and door systems, the reinforcement steel maintains durability of the systems by keeping their integrity and shape for years. Our reinforcement steel are offered to our customers after packaging in appropriate weight by full-automatic machines to protect against exterior effects.

GENERAL INFORMATION

Wall thickness of the reinforcement steel should be appropriate for the usage conditions of PVC window and door systems. For example, the reinforcement steel not having appropriate wall thickness in case of high buildings (6+ storeys) fail to stand against wind load, causing the system to suffer damage, leading to air and water permeation in time. Structure and shape of the reinforcement steel should be very neat. The reinforcement steel with deformed shape and structure cause change of the profile shape, leading to damage of the functional structure of the system.

The gap between the reinforcement steel and inner surface of the plastic profile should be minimum 1mm and maximum 2mm. If the gap is more, then the resistance reduces, preventing proper screwing. If the gap is less, then it prevents expansion of the plastic profile, causing cracks.

Longitudinal cutting of the reinforcement steel should be adjusted by leaving proper melting distance at the welding points of the profile. Melting distance should be left at both directions, namely, 10 mm from the profile length in case of cuttings by 90º and 7.5mm in case of 45º. The reinforcement steel should be definitely used as single piece in the opening where it will be used. When it is used as pieced, it would give damage to the system.

Even when using the shortest length, the reinforcement steel should be screwed minimum at two points. Screw interval should be maximum 30-40 cm. It should be screwed at a maximum of 15 cm inwards from the starting point.

The reinforcement steel should be cut carefully with the edges smooth and free of burrs, and the saw should be operated at low rotation

The reinforcement steel should never be stored outdoors; there should be no rain, water, moisture and contact with floor in the storage area. There should be no excessive temperature differences in the storage area and long time storage should be avoided.
