Explore our flagship heavy-duty security structures, copper armored variants, and bespoke interior flush doors designed for architectural luxury.
Zhejiang Larsom Door Co., Ltd. leads the evolution of high-security architectural barrier systems.
As a specialized, R&D-driven manufacturer, we bridge the gap between heavy structural engineering and high-end exterior aesthetics. Our advanced armored doors are built to secure villas, luxury apartments, and commercial environments globally, combining structural core integrity with corrosion-resistant, customized copper cladding designs.
Our armored cores leverage high-density multi-point steel frameworks, double-layer hot-dipped galvanized sheets, acoustic-damping rockwool, and structural thermal breaks. This complex layering guarantees robust security ratings, class-leading thermal insulation, and decibel-reducing soundproofing.
Our manufacturing capabilities cover a modern footprint of over 16,000 square meters in Zhejiang, backed by a workforce of 160+ industry specialists. With a stable daily output exceeding 200 sets of customized doors, we supply complex building projects and fast-moving wholesale demands across Europe, the Middle East, Central Asia, and the Americas.
How Larsom integrates mechanical strength with metallurgical innovation to meet the future of security entryways.
Utilizing high-purity copper and brass overlays bonded directly to double-galvanized sub-layers. Our oxidation-control process slows down natural aging while preserving copper's natural antimicrobial properties and architectural depth.
Thermal bridging is a major flaw in metal doors. Larsom integrates polyacrylamide-reinforced glass fiber (PA66) thermal break profiles to split inner and outer frames, drastically lowering heat transfer in extreme climates.
Direct pre-engineering of the internal steel plate chassis to house high-torque motor locks, biometric access, and concealed wiring paths, preventing damage during retrofitting and ensuring long-term system stability.
Precision fabrication workflows translating into unbeatable lead times and structural tolerances.
Different markets present unique legal hurdles and functional constraints. Larsom designs doors to meet international building codes head-on.
For prestige properties demanding high visual appeal. Our custom copper panels, matching wood veneer inner skins, and hidden heavy-duty pivot hinges provide clean architectural profiles with multi-point anti-drill locks.
Meets strict international requirements (UL, CE, BS 476). Steel cores are paired with mineral core fire boards and cold-formed frame structures to ensure heat protection up to 120 minutes while retaining ballistic ratings.
We provide structural knock-down (KD) frames for flat-pack container optimization, significantly lowering shipping overheads. Every batch is shipped with high-precision installation templates to expedite on-site assembly.
