Long-Term Supply Relationships

Heavy Industry

SANY Heavy Industry

Long-term supply of conveyor idlers and rollers for SANY material-handling equipment. Requires dimensional consistency across repeat batches — the reason robot welding and in-line inspection are on our floor.

Heavy Industry

ZOOMLION

Conveyor components supplied to ZOOMLION equipment programmes, with documentation and traceability to support their incoming quality system.

Tunnelling & Heavy Equipment

CRCHI

China Railway Construction Heavy Industry — components for muck-handling conveyors, where abrasive spoil and continuous duty decide service life.

Steel

China Baosteel

Steel-works conveying duty: radiant heat, abrasive sinter and scale. Reinforced shafts and heat-appropriate material selection.

Power Generation

Huaneng Power

Coal-handling conveyors for power generation — high tonnage, continuous operation, dust-heavy transfer points.

Machinery

Sheng Hong Machinery

OEM supply of idlers, pulleys and frames to drawing, integrated into their own conveyor systems.

Mining · Brazil

Vale

Supply relationship with Vale, one of the world's largest iron ore producers — the reference that opened doors for us across Latin American mining.

What These Accounts Have in Common

Three Things Buyers Qualify Us On

01

Batch-to-batch consistency

Automated cutting, welding and assembly mean the 10,000th roller matches the first — the requirement every large account audits for.

02

Documentation & traceability

Per-unit ID tagging, material certificates and inspection records that survive their incoming QC process.

03

Engineering response

When a duty condition changes, we re-specify material, seal or coating rather than shipping the same part again.
