A: For standard warehouse loading docks (3-4m wide, 3-4m high), overhead sectional doors are the most popular choice — they provide good insulation, fast operation, and roll up vertically to save interior space. For high-traffic docks (50+ operations/day), high-speed roller doors (PVC or aluminum) with 1-2 second opening speed reduce energy loss. For very large openings (6m+), industrial sliding doors or folding doors are more economical. We recommend based on: opening size, frequency of use, insulation requirements, wind conditions, and budget.
A: As a general guideline, skylight area should be 5-10% of floor area for warehouses and factories. This provides 300-500 lux of natural daylight at floor level on a sunny day, sufficient for most industrial tasks without artificial lighting during daytime. For precision work or offices, 10-15% skylight ratio is recommended. FRP skylights with 50-75% light transmission are most common — they provide bright but diffused light without glare. We calculate optimal skylight placement based on: building orientation, roof slope, latitude, local sunshine hours, and interior usage requirements.
A: Yes, all our doors and windows are designed for straightforward installation by local contractors. We provide: (1) detailed installation drawings with anchor bolt locations and rough opening dimensions; (2) step-by-step installation manuals (in English, with photos); (3) pre-assembled door/window units with all hardware attached; (4) video installation guides for complex products; (5) remote technical support via WhatsApp/email during installation. For first-time installations, we recommend a 1-2 day remote supervision session with our engineer. Typical installation time: 2-4 hours per overhead door (2 workers), 30-60 minutes per personnel door/window.
A: For coastal areas (within 50km of coastline), we recommend doors and windows designed for minimum 0.7 kN/m² wind pressure (equivalent to ~120 km/h wind speed). For hurricane/cyclone zones (e.g., Philippines, Caribbean, Gulf of Mexico), use 1.0-1.5 kN/m² rating with reinforced tracks, impact-resistant glazing, and additional anchor points. Our standard doors are rated for 0.5 kN/m²; reinforced options add 15-30% to cost but prevent catastrophic failure during storms. We provide wind load calculations per local building code (ASCE 7, EN 1991-1-4, GB 50009) for every project.
A: Yes, we supply fire-rated personnel doors with 30, 60, 90, and 120 minute ratings, tested per EN 1634-1 and ASTM E152. Each door comes with: (1) third-party test report from accredited laboratory; (2) CE marking (for EU projects); (3) fire door label with rating and manufacturer code; (4) intumescent seals and fire-rated hardware (hinges, locks, closers). Fire doors are required for: fire exits, stairwell enclosures, equipment rooms, hazardous material storage, and connections between fire compartments. We provide fire door schedules as part of our complete building package, ensuring compliance with local fire code.
