Common support skeletons (commonly known as tent poles) have four kinds:
1, Steel pipe: Also known as high-frequency welded pipe, mainly used in military tents, relief tents and other large tents above, the surface has sprayed or galvanized treatment, there is a round tube and square tube, the diameter of the general in the 19~50mm unequal, wall thickness in 0.8~3mm.
2, elasticity just: This kind of generally is the children's account or beach game account.
3. Fiberglass Rod: There are 6.9/7.9/8.5/9.5/11/12.5 series. The thicker the rigidity the stronger, the softer the weaker. Therefore, the choice of the stent is reasonable according to the size of the ground and height of the proportion of the decision, too coarse and meticulous are easy to break. For example: 210*210*130 is a relatively classical size, with pipes typically 7.9 or 8.5. 4, aluminum alloy skeleton: Compared to high-grade, according to the alloy matching test is also difficult, generally its original bracket overall radian curve, are first calculated and then hot-pressing shape treatment. The characteristic is the light carry convenience main still is not easy to fold, but the quality is not easy bending deformation.
