Appliance Factory — Monterrey, Mexico

Industrial buildings in Mexico must comply with NOM (Mexican Official Standards) and local municipal approval, with steel typically required to meet ASTM standards. ZhongSai provides material certificates compliant with ASTM A36/A992 standards, factory inspection reports, and welding procedure specifications to assist clients with local approval and NOM certification processes.

This project is equipped with 4 units of 5-ton overhead cranes, using a double-slope rigid frame structure with 9-meter column spacing and 24-meter span. The crane beam uses welded H-section steel with checkered plate brake plates, and the crane beam is connected to columns with high-strength bolts. Structural calculations consider crane vertical loads, transverse horizontal loads, and longitudinal horizontal loads to ensure safety during simultaneous operation of multiple cranes.

Monterrey is located in a seismically active zone, with seismic fortification intensity designed at 8 degrees. The structure uses a rigid frame system with hinged column bases and rigid beam-column joints, with full penetration groove welds at beam-column joints and concentric bracing systems between columns. Structural calculations consider both frequent and rare earthquake conditions to ensure 'no damage under minor earthquakes, repairable under moderate earthquakes, no collapse under major earthquakes'.

Sea freight from Shenzhen to Manzanillo Port takes approximately 25-30 days, and customs clearance after arrival typically takes 5-10 days. We recommend clients prepare import permits and NOM certification in advance. ZhongSai provides complete packing lists, commercial invoices, certificates of origin (eligible for USMCA tariff preferences), and material certificates to ensure fast customs clearance.
