Prefab Steel Structure Products

● PU sandwich panels usually provide stronger thermal insulation at a thinner panel thickness than rockwool panels. ● Rockwool panels are typically preferred when fire resistance and sound absorption are the highest priorities. ● In humid or temperature-controlled projects, PU sandwich panels often perform better in moisture resistance and enclosure efficiency. ● Rockwool panels are heavier, which can influence handling, installation speed, and support structure design. ● The better choice depends on the building’s fire code, insulation target, operating environment, and lifecycle priorities.

● Sandwich panels can often be repaired without replacing the entire roof. ● Most leaks start at joints, screws, flashing, or roof openings rather than the panel core. ● Local sealing, refastening, and patch repair work well when damage is limited. ● Wet insulation, crushed joints, or repeated leakage usually point to panel replacement. ● Repair quality depends on drainage, detailing, and compatible replacement materials.

● A Pre Engineered Steel Building is factory-designed and site-assembled for faster construction. ● Pre Engineered Steel Building systems are common in warehouses, workshops, factories, and storage buildings. ● Main strengths include shorter schedules, efficient steel use, flexible spans, and easier future expansion. ● Cost depends on span, height, loads, cladding, insulation, accessories, transport, and installation conditions. ● Good performance relies on accurate design, suitable specifications, and proper erection quality.
