Hebei Qierjie New Energy Technology Co.,Ltd, professional manufacturer for Seismic Bracing products, hex bolt galvanized, the main parts for seismic bracing project during building construction installation.

Hexagonal bolts are hexagonal head bolts (partial threads) – class C and hexagonal head bolts (full threads) – class C. Also known as hexagonal head bolt (rough) wool hexagonal head bolt, black iron screw. Commonly used standards can be referred to:: DIN 933, DIN 931, DIN960, DIN961, DIN609,high strength bolt, also can do with your drawings.

Hot-dip galvanized bolts refer to special bolt products produced through heating galvanizing treatment, which are widely used in industrial infrastructure construction and mechanical processing. Hot-dip galvanized bolts are degreasing and derusting to present a non-polluting and infiltrating surface. They are immediately immersed in a plating tank where zinc has been heated and melted in advance to form a zinc coating on the surface of the bolts.

Due to the thickness of the coating, hot-dip galvanized bolts are not compatible with other nuts. The threaded holes of galvanized nuts are slightly larger than other nuts to accommodate this coating. Hot-dip galvanized fasteners are often found in coastal environments and pressure-treated wood. The chemicals in these woods may corrode other fasteners.

Hexagonal bolt: A type of fastener consisting of a head and a screw (a cylinder with external threads), which needs to be matched with a nut to fasten and connect two parts with through holes. This connection form is called bolt connection. If the nut is screwed off from the bolt, the two parts can be separated, so the bolt connection belongs to the removable connection.

Seismic support is a variety of components or devices that limit the displacement of the attached mechanical and electrical engineering facilities, control the vibration of the facilities, and transfer the load to the bearing structure. The seismic support should give reliable protection to the building mechanical and electrical engineering facilities in the earthquake and withstand the earthquake from any horizontal direction; Seismic support should be checked according to its load; All components of the seismic support shall be finished components, and the components connected with fasteners shall be easy to install; The limit of the anti-seismic support of the insulation pipeline should be designed in accordance with the size of the pipeline after insulation, and should not limit the displacement of the pipeline caused by thermal expansion and cold contraction.

After seismic reinforcement of building water supply and drainage, fire protection, heating, ventilation, air conditioning, gas, heat, electricity, communications and other mechanical and electrical engineering facilities, when encountered in the region of seismic fortification intensity of the earthquake, can achieve the reduction of earthquake damage, reduce and as far as possible to prevent the occurrence of secondary disasters, so as to reduce casualties and property losses.
