Steel Truss

The steel truss structure is a beam-type component, which is a "free-web type beam" composed of multiple small-section rods. It is a statically determined structure. Because its cross-section can be made very high, it has a large bending resistance and small deflection, which can be suitable for a larger span than a solid web beam, saves steel materials, and has a small structure weight and is not bulky.

(1) Aluminum welded truss: lightweight, novel and beautiful in appearance, and can be used in various booth shapes;

(2) Butterfly truss: It can be widely used in exhibitions in various industries and is easy to disassemble and transport;

(3) LH series: The perfect combination of straight pipes and inclined pipes, which can be widely used in booths of various shapes. The fully assembled structure is easy to install and disassemble, and can achieve long-span connections.

1. Precise design verification: Calculate loads (dead load, wind load, etc.) in accordance with standards, verify the internal forces of members and the bearing capacity of nodes using professional software, and select matching steel materials (such as Q355B) to ensure structural safety under load.
2. Strict material control: Check the steel material certificates and quality certificates, conduct random tests on mechanical properties, and ensure that auxiliary materials (such as bolts and welding rods) match the main materials. Unqualified materials are strictly prohibited from entering the site.
3. Factory precision processing: Use CNC equipment for cutting and hole-making, control the precision (such as the length deviation of members ≤ ±3mm), follow the welding process, conduct 100% non-destructive testing on critical welds, and ensure rust removal and anti-corrosion meet standards.
4. Standardized on-site installation: First measure the reference points, install in sequence (such as from the middle to both ends), adjust the verticality and elevation after temporary fixation, ensure the final tightening torque of bolts meets standards, and conduct secondary non-destructive testing after welding.
5. Comprehensive acceptance inspection: Inspect the processing and installation quality at each stage, conduct an overall load test before completion, check welds, bolts, anti-corrosion, etc., and keep complete records to ensure full control throughout the process.
