Every weldment is shot blasted to Sa 2.5 and painted in a full-size booth with treated exhaust.

S355JR and Q355B are widely treated as counterparts. They are close — but not the same document.

Pin bores and lug clusters are assembled on dedicated fixtures — 1 mm fit-up limits and symmetric welding keep alignment.

We weld with argon-CO₂ mixed gas rather than straight CO₂ — less spatter, flatter beads, less cleaning.

We have received a custom request for a Heavy duty bucket（Universal cut）. The client needs to dig through dense and abrasive materials such as hard ground, gravel, and rock. It features extended side and bottom wear protection along with a high abrasion tooth system  to enhance durability. Finally, we make it.

We have received a custom request for an ultra long boom. The client needs to operate at a very high position—let’s see exactly how long it needs to be.
