The welding structure of the project is designed and manufactured according to the Asime B29.16m "Steel Welding Engineering Chain, Annex and Spicy Rice" and ISO 6972 "Welding Structure Engineering Engineering Engineering Candid Chain Annex". For options, you can also customize development according to user needs. Welding curve chain (abbreviated) is a type of steel curved chain. It is welded by two coop plates and sleeves (no rollers) to form the curve chain joint. The number of chain sections of the entire chain can be even or odd. The chain section is processed by advanced and high -efficiency welding equipment to ensure that the welding quality is reliable. There are two types of different tensile strength indicators of WR series and WH series.

The welding board chain is mainly suitable for low -speed overload, large impact, material wear, and a poor working environment containing a large amount of dust. It has a lot of applications in the field of forest and wood.
