Steel door Lain


The Lain metal door for offices, administrative and technical premises, apartments and houses are custom-built to match the individual dimensions.

May be installed on the outside or inside a building.

At our factory, the Lain metal doors are manufactured from 1.5 mm single-piece bound steel sheets; this door has a thin rebate and a 52 mm thick leaf. A durable shaped tube frame also forms the case.

Powder coating (glossy, matt or structural) improves the door’s anticorrosion and shockproof capabilities and allows any tint to be chosen from the RAL catalogue. Doors with powder coating are deemed to be the most durable and most resistant to any kinds of impact.

Serial Lain steel door can be used a film as a coating, which imitate the structure of wood.
  • These may be single- or double-leafed, glazed, with an upper or side transom, fitted with a door check and other systems.

    You can also feel free to order unconventional doors of any complexity – we will try to find the optimal solution for you.
