welding of screw pile

Technical Requirement on Welding of Screw Pile

Welding of screw pile HS Metal professionally produce screw pile and give special attention on details.  Locate welding point of the helix plate according to specified requirement. Width of welding of helix is 3 mm, no bubble,no fake welding. Reinforce welding at start and stop point of helix on screw pile shaft. Handle with care to avoid transformation of the helix and shaft ends. Nuts on the ground screw must be lo

Hot Dip Galvanization and Cold Galvanization

Difference between Hot Dip Galvanization and Cold Galvanization There are two kinds of galvanization pipe: cold galvanized and hot dip galvanized(HDG). The former one has been prohibited, the later one is now temporarily encouraged by China. HDG is to do pickling of pipe firstly so to remove iron oxide on the surface. After pickling, wash pipe in the tank which mixed with ammonia chloride and zinc chloride, then have

Hot dip galvanization

Hot Dip Galvanization Introduction Ground screw is widely used as foundation of PV solar system,fencing,house construction etc. Pole anchors, wood connectors are used to fasten objects. Hot dip galvanization is to be performed to anti-rust and guarantee life of ground screw,post anchor. Hot dip galvanization includes below steps: 1. Remove pollutants from to-be-galvanized products; 2. Do pickling and then rinse with

Automatic shrinking machine for ground screw

Ground screw pile is made of conical steel pipe and helix. To make conical pipe ends, the usage of automatic shrinking machine frees most of man power and improves the production. After heating from the induction coil, heated pipes are loaded onto automatic shrinking machine and finish shrinking stage.

Hardness of Metal Timber Connector

Hardness of Metal Timber Connector Metal timber connectors are used to bind timber to timber, timber to steel, timber to concrete. Hot dip galvanization could protect wood connector from corrosion. And hardness of timber connector bracket itself is very important to its quality. Heavy timber metal connector is made of steel plate, after cutting, bending, flattening, forming, calibrating etc, wood connector is made th

Metal stamping parts

Advantage of Metal Stamping Parts Metal stamping parts are processed by shaping raw material (sheet metal) to form into different size with various shape of metal with certain performance by die. Drawing, raw material, die, and punch press machine are top 4 elements to fabricate sheet metal. Metal stamping parts are manufactured by cold processing which is the most useful way to proceed precision metal stamping, it&#
