The Foundation of Every Great Building
Lanying structural systems are designed to provide maximum flexibility and efficiency for a wide range of building applications. Our pre-engineered approach combines advanced computer-aided design with precision manufacturing to deliver structures that are stronger, lighter, and more cost-effective than traditional construction methods. From single-span warehouses to complex multi-story buildings, every structure is custom-engineered to meet specific project requirements, local building codes, and environmental conditions. Our systems can accommodate spans up to 100 meters, heights up to 30 meters, and virtually any roof slope or exterior finish requirement.

Find answers to common questions about this product
Our portal frame structures can achieve clearspans of up to 36 meters for single-span configurations. For larger spans, we recommend multi-span designs or space frame/truss alternatives that can exceed 100 meters.
Fabrication time depends on building size and complexity. A typical 1,000 m² warehouse can be fabricated in 4-6 weeks. Larger or more complex projects may take 8-12 weeks. Our pre-engineered approach is 30-40% faster than conventional methods.tion.
Yes. Steel structures have excellent seismic performance due to their high strength-to-weight ratio and ductility. Our structures are designed to comply with seismic Zone 4 requirements and can withstand intensity 8 earthquakes.
We offer hot-dip galvanizing (HDG) for maximum corrosion protection, shop-applied primer and topcoat paint systems, and combination treatments. The choice depends on the building environment and required design life.
