PACKAGING AND SHIPPING

Packaging:
The steel is closely packed to protect the surface and maintain the stiffness when handling and transporting. The items are generally wrapped using water proof material, plastic wrap or rust proof paper and the small accessories are contained in wooden boxes. All bales or panels are well marked for differentiate, which is also would facilate the safe and high efficient unloading and installation on site.

Transportation:

Steel building materials are shipped by container or bulk carrier based on size and destination. Heavy or large parts are tied down tightly with steel strapping and wood bracing to prevent shifting or bending while in transit. All the logistics meet the standard of the international transportation, so we can guarantee the delivery in time, and also keep the safety even the long distance or the ocean going ship.

FAQ

Regarding Material Quality
Q: What standards do your steel structures comply with?
A: Our steel structures comply with American standards such as ASTM A36, ASTM A572, and ASTM A588. For example, ASTM A36 is a commonly used carbon structural steel with good overall performance, while ASTM A588 is a high - weather - resistant structural steel suitable for harsh environments.

Q: How do you ensure the quality of steel materials?
A: We source steel materials from well - known domestic and international steel mills with strict quality control systems. All materials undergo strict inspection upon arrival, including chemical composition analysis, mechanical property testing, and non - destructive testing such as ultrasonic testing and magnetic particle testing, to ensure that the quality meets the relevant standards.

Regarding Corrosion Resistance
Q: Given the humid and high - temperature environment in some parts of the Americas, how does your steel structure prevent corrosion?
A: We usually use hot - dip galvanizing treatment for steel structures. The zinc layer thickness can reach more than 85μm, which can effectively isolate the contact between steel and the air and moisture, thereby enhancing corrosion resistance. In addition, for some parts with higher corrosion requirements, we can also apply anti - corrosion paints, such as acrylic anti - corrosion paints, which have good UV resistance and can maintain good anti - corrosion performance for more than 10 years.

Q: Does the corrosion - resistant treatment affect the strength and other properties of the steel structure?
A: The hot - dip galvanizing treatment and the application of anti - corrosion paints will not have a negative impact on the strength and other properties of the steel structure.
On the contrary, proper corrosion - resistant treatment can protect the steel structure from corrosion, thereby maintaining its original strength and performance for a long time and extending its service life.

Regarding Structural Design and Safety
Q: Can your steel structure meet the seismic requirements in the Americas?
A: Yes, our steel structure design takes into account the seismic characteristics of different regions in the Americas.
We adopt high - seismic - resistant node designs, such as bolt - connected joints, which can effectively absorb seismic energy and avoid brittle fracture of welds during earthquakes.At the same time, we will conduct seismic calculations according to local seismic intensity requirements to ensure that the steel structure has sufficient seismic performance.

Q: How do you ensure the overall stability of the steel structure?
A: Our steel structure design is based on strict mechanical calculations and engineering experience. We reasonably arrange the main load - bearing structures, such as portal frames, columns, and crane beams, and set up a complete support system, including tie bars and corner braces, to enhance the lateral stability of the structure and ensure that the steel structure can safely bear various loads under normal use and extreme conditions.
