Cutting, fit-up, welding, blasting and coating all happen on the same site in Jinzhou. That is why a member reaches your site at ±3 mm — and why we can give you a date and hold it.
A drawing is only as good as the machine that follows it. These are the six that decide whether your member fits on site.
Plate nested and cut straight from the model, so the cut list and the drawing cannot drift apart.
Flange and web cut square in one pass, with copes and bolt holes burned at the same setting.
Web and flange clamped square on a fixed bed before the first pass goes down, not after.
Saw and weld ride the same gantry, so a long seam runs without being turned by hand.
Box sections squared and clamped on a hydraulic bed, then welded in sequence to hold the twist out.
Stiffeners, base plates and folded sections pressed in house, so they arrive on the day the beam does.
Five bays, one direction of travel. Nothing doubles back, and nothing waits in the open for a truck that is not booked.
Plate and section cut to the model, offcuts tagged back into stock the same shift.
Members assembled square, with the mark number painted on before welding starts.
Gantry seams first, then the connections. Every main seam passes ultrasonic before it leaves.
Shot blasted to the agreed grade, primed and finished to the dry film thickness on the drawing.
Bundled by erection sequence, so the piece you need first is the piece you unload first.
Four 150-Mts overhead cranes run the heavy bays, with 50-Mts units on the lighter lines. That is not a number for the brochure — it is what lets a deep plate girder be turned, trial-assembled and loaded whole, instead of being cut into pieces that have to be spliced again on your site.
It also decides what we can quote. Trusses and transfer girders that other shops decline because they cannot be handled are ordinary work here.
No price, no obligation — an engineer reads your plan and tells you where the cost and the trouble usually sit.
