Frame Structure
It is connected by multiple rods and ball node bolts to form a stable triangular structure, which is one of the main stress-bearing components of the building.
Truss Structure
Multiple rods and main pipes are welded together to form a stable triangular structure, which serves as one of the main stress-bearing components of the building.
Steel Structure
Factory-made steel beams and various steel components form one of the main stress-bearing components of various buildings.
Design
We design detailed drawings for free and can provide design models to facilitate your review of structural safety and engineering quantities to ensure the safety of your project.
Manufacture
Using factory assembly line production can reduce costs and save time, greatly shortening the construction period of your entire project.

I. Definition of High-strength Bolts for Space FramesHigh-strength bolts for space frames are mainly used in bolt ball joints.By connecting the bolt, conical end, and bolt ball, they enable spatial force transmission among member elements.They resist:Axial tension or compression of the boltShear force at the jointTransfer of nut pretensionLocal bearing forces at the jointII.

I. Definition of Bolt Ball JointA Bolt Ball Joint is the most commonly used node form in space frame structures. It connects members through the combination of bolt + conical end + spherical body, enabling spatial force transfer between steel pipe members.Components:Bolt ball (solid spherical body)High-strength boltConical end (cone head)Washer and nutMain Functions:Converge multiple tubular members at the center of the ball jointTransfer forces in a three-dimensional spaceEnsure node stiffness and overall structural stabilityII.
