Door leaf
The door leaf, including the ends of the panel, is made of steel sheet 0.5 mm thick, resistant to mechanical shock and stress.

Depending on the degree of aggressiveness of the working environment, it is possible to manufacture doors from stainless steel AISI **4 for food or AISI **0 for non-food. Internal embedded elements of the door leaf ensure reliable fastening of the fittings. All doors are equipped with an elastic seal. Protection of the door leaf from damage is ensured by a special polyethylene film *0 microns thick, which can be freely removed after installation.

Thermal insulation
Thermal insulation is provided by the door filling: high-quality rigid polyurethane foam (PUR) with a density of up to *0 kg / m³.

Door frame
The doors are equipped with a rigid metal profile frame.

There are three options for making the frame:
