Northline Industrial Co., Ltd.
Every part is made to a customer drawing or specification. The ranges below are what we can hold without special tooling; anything outside them starts with a conversation, not a rejection.
Welded chassis sections
Main frames and sub-frames for construction and agricultural equipment. Plate 6–40 mm, jig-built with fixed datum points for repeatable assembly at the customer's line.
Wear liners and buckets
Wear plate components for mining and aggregate handling. Hardness 400–500 HBW, with optional hardfacing on the highest-wear edges.
Boom and arm assemblies
Long-reach structures that must not deflect under load. Stress-relieved after welding, then machined in a single setup to keep bore alignment.
Machined plate components
Brackets, flanges, adapter plates and counterweights. CNC machining up to 3,000 mm, tolerance to ±0.1 mm on critical features.

What we need to quote
Send the drawing and we will reply within two working days with price, lead time and any tolerance we cannot hold. If the drawing is incomplete, we will tell you what is missing rather than guess.
- Drawing in PDF, DXF or STEP
- Material grade (or the application, if the grade is open)
- Annual volume and shipment pattern
- Destination port, if you want the freight included
- Any certification the end customer requires
