Reinforcement steel is one of the fundamental parts of PVC window ad door systems, forming bearing structure of the system and giving resistance to the plastic profile.

On PVC window and door systems, the reinforcement steel ensures more powerful adherence of the systems with each other and of the hinges with the plastic profile, giving plastic profile its shape and ensuring it to maintain its structure for long time.

FIRAT reinforcement steel are manufactured in hot dipped galvanized class as per TSE 822 with zero fault 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 apart even when shaped by bending. It is resistance against fire and all kinds of exterior effects. Loss of coating thickness is minimum under normal air conditions. Raw material is always kept subject to quality control test at our advanced laboratories throughout all stages before, during and after production. Forming skeleton of FIRAT PVC window and door systems, the reinforcement steel maintains their integrity and shape for years, making the systems more durable.  Our reinforcement steel are offered to our customers after packaging by full-automatic machines in appropriate weight 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 fail to stand against wind load, causing the system to suffer damage, leading to air and water permeation in a course of time. Structure and shape of the reinforcement steel should be very regular. 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 part in the opening where it will be used. When it is used in parts, 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 by going into max. 15cm from the starting point.

When cutting the reinforcement steel, care should be shown that the ends should be smooth, free of burrs, and the saw should be operated at low revolution.

The reinforcement steel should never be stored outdoor; there should be no water, moisture and contact with floor in the storage aria. And furthermore there should be no excessive temperature difference in the storage area and you should avoid of storage for long time.
