The inner wall of the pipe is treated with anti-rust spray paint, and the anti-rust layer is tightly adhered to the inside of the pipe, which is not easy to fall off.


During the production process of lean pipes, high-pressure gas is injected into the interior of the lean pipes through an air gun for inspection to eliminate any missed welds or perforations, ensuring the safety of each lean pipe.
Even coating can make the metal joint better fit with the coating pipe.Then can reach the requirement of assembling.


There are two at the head and two at the tail of the metal joint.A jagged stiffener arranged in three columns. It is increase the clamp force,pulling and meet the safety requirements.
The edge and acute angle of metal joint adopted the humanized arc structure design. Protecting product and user safety.


Two assembly identification lines are added to the tail of the metal joint. Improve assembly efficiency and avoid assembly error.
The planer pivot and bearing support of aluminum roller track is T1.6MM and T2.5MM. The design requirements of bearing capacity improve the bearing capacity of roller track.It is meet the use requirements of carrying capacity.


The bearing support of iron roller track height is 15MM. The design requirements of bearing capacity improve the bearing capacity of roller track. It is meet the use requirements of carrying capacity.
Reduce friction, enhance rolling performance and load-bearing capacity. The two bead tracks can distribute the load, thereby improving the overall strength and stability of the casters. Enhanced durability: Casters with a double-bead track design are usually more durable than those with a single-bead track design. The rolling contact method of steel balls or balls is more resistant to wear than the sliding contact, thereby extending the service life of the casters.


Double-bearing casters can bear greater weight and rotate flexibly. Double-bearing casters rotate more smoothly. The double-bearing design enhances the stability of the casters and reduces malfunctions caused by excessive load or frequent movement.
