Yes, you are highly welcome to visit our manufacturing factory. You can fly to our nearest international airport, and we will pick you up at the airport for a comprehensive guided tour.
Our objective is to deliver the absolute best pricing without compromising on material quality. We constantly optimize our manufacturing techniques to minimize production expenses, ensuring you receive maximum product value for your investment.
Yes, we provide fully customized engineering design solutions. Utilizing industry-standard design tools like AutoCAD, PKPM, 3D3S, and Tekla Structures (X-Steel), we can design complex industrial complexes, office buildings, shopping centers, and multistory hotels.
Delivery timelines vary based on the specific structure complexity and order volume. Generally, dispatch to the nearest domestic sea port in China takes around 30 days after our receipt of your initial deposit.
We typically build structures using widely-approved structural steel grades such as Q235, Q345, and ASTM A36. These materials provide the ideal combinations of high yield strength and long-term durability depending on your custom load demands.
Our prefabricated systems provide exceptional seismic resistance, clear large-span spaces, and lightweight strength. The modular elements allow fast construction schedules, often shortening overall building erection times by up to 50% compared to traditional masonry.
