steel external doors

The offer of steel external doors is addressed to investors looking for external entrance doors characterized not only by good thermal insulation and attractive design, but also by a solid construction and a high level of anti-burglary protection.
Steel exterior doors are a fairly common choice for customers planning to build or renovate a home due to the relatively low cost of purchasing and operating such doors while ensuring good thermal and acoustic insulation, a high standard of burglary protection, and an exceptionally wide selection of door types, colors, and patterns. The production technology for steel exterior doors and the materials used allow for an extremely diverse and interesting design, significantly enhancing the aesthetic qualities of the buildings in which the exterior doors are installed.

The construction of an exterior door leaf is comprised of a system of steel sections or laminated hardwood frames. The leaf sheathing is made of galvanized steel sheet, 0.7 to 1.0 mm thick, flat or with decorative embossing. The steel sheet covering the leaf is coated on the outside with a wood-like laminate and can also be powder-coated. The door leaf, made of 1.0 mm thick sheet metal, can be embossed in several patterns up to 2.0 mm deep, while the 0.7 mm sheet metal sheathing allows for embossing up to 5.0 mm deep, further enhancing the door's aesthetics and expanding the design choices. The door leaf's infill ensures adequate rigidity and, above all, appropriate thermal and acoustic insulation properties. Depending on the type of external door, the filling of the leaves is made of high-density polyurethane foam, polystyrene boards, foam with reinforcement in the form of steel rods or mineral wool boards glued to the sheet metal of the leaf covering.

Hardware for external steel doors in residential buildings

combines functionality with aesthetics, contributing significantly to both the appearance and security of the entire door system. Modern handles, escutcheons and pull handles can complement the architectural style and create a coherent visual effect with the door finish. Equally important are secure locks and cylinders, which help protect the entrance against unauthorized access. Properly selected hardware provides comfortable everyday operation, durability and reliable performance, combining contemporary design with practical security requirements.

Heat loss from the residential building is prevented by highly elastic door seals embedded in the rebate of the door leaf on the top, lock, and hinge edges. The lower edge of the door leaf can be equipped with a comb seal, automatic drop seal, or adapted for sealing with a finishing threshold with an EPDM seal. An additional sealing surface in the frame significantly reduces energy loss. Multi-point locks, lock cylinders, and security pins on the hinge side provide an appropriate level of burglary protection for exterior doors. The steel door leaf is mounted in the frame on three hinges equipped with Teflon spacers and anti-knockout pins. The hinges allow for two-way adjustment of the door leaf position. The aesthetics of the hinges are enhanced by covers matched to the door leaf's color or hardware.
