Eight advantages of expansion screws:
1. Wide applicability. As long as the male thread size is the same, it is suitable for any type of anchor head.
2. Selection of construction method. The point preset can be selected according to the requirements, or the drilling can be installed (loaded) in a single construction, and its function and effect are completely consistent.
3. High construction success rate. There is no hole depth attachment and drilling inclination, and the construction achievement rate is 100%.4, high 亢 pull design. Full-tooth taper expansion special inverted hook design.
5, lock the anti-loose effect. The full-tooth taper expansion is specially designed to lock the workpiece tightly with the reverse thrust effect.
6. Improve design thinking. Short and simple, it is suitable for all the commercially available screws, DIY and the most desirable construction options for the fortifications.
7. Ensure anchor bolt expansion. Metal plate pressing products, patented full-tooth taper expansion design, strong gripping ability, no need for professional construction skills.
8, abandonment without trouble. As soon as the anchor part is withdrawn, the filling agent is applied to restore the plane, without the trouble of resection and the danger of the impact of the protrusion.

Alloy steel refers to steel with high strength and good chemical stability at high temperature. It includes two types of anti oxidation steel (or high temperature resistant steel) and hot steel. Anti oxidation steel generally requires good chemical stability, but the capability is limited. High temperature strength and the corresponding oxidation resistance of heat and strong steel are required. Heat-Resistance Steel is often used in the manufacture of boiler, steam turbine, power machinery, industrial furnace and aviation, petrochemical and other industrial sectors in the work of the high temperature parts. In addition to the requirements of high temperature strength and high temperature oxidation corrosion, sufficient toughness, good shaping and welding are also required according to the different use, as well as a certain organizational stability. In addition, some new low chromium nickel oxidation are also developed .
