ERW & HF Welded Round Steel Pipe
The round-pipe range for the ZT straight-seam series and the HG coil-fed lines — outside diameter, wall thickness and line speed for each model, with the standards the pipe is specified to.
Download PDF · 1 pageDatasheets & Downloads
One-page specification sheets for welded steel pipe and tube — model ranges, wall thickness, line speed, and the standards each product is specified to. Every sheet is a single page, sized for forwarding to a colleague or attaching to a tender.
Published values, not invented ones
The size and speed figures in these sheets are the ranges published on the corresponding machine page. The standards are cited by designation and scope — grade, mechanical values and tolerances are governed by the standard, not by a measurement of a particular production batch. Where the standard leaves a value to the producer, the sheet says so rather than picking one. Grade, coating and end finish for your order are confirmed at quotation.
Square & Rectangular Hollow Sections
Section range, wall thickness and cut-length tolerance for the two lines we build in square and rectangular format, plus the standards hollow sections are bought to.

The three ZT stainless units — tube OD, wall thickness and line speed — and why stainless lines run at a fraction of carbon-steel speed.

A one-page selector covering ASTM A53, A500, A513, A252, EN 10255, EN 10219, EN 10217, GB/T 3091, GB/T 6728 and API 5L: what each one covers and when buyers choose it.

SL-1250 and SL-1600 side by side — strip material and thickness, coil size and weight, width tolerance (+/-0.05 mm), line speed and footprint, and what actually decides slit-strip quality.

Cantilever and hydraulic decoilers with their coil limits, and the cold-cutting flying saw — cutting method, tracing, and the +/-2 mm cut-length figure the servo tracing holds.
Download PDF · 1 pageLaser vs High-Frequency Welded Tube Mill
The laser line specification (round 32–96 mm, square to 75×75, wall 0.8–2.5 mm, 6000 W welder) plus a plain statement of when laser wins over HF welding and when it does not.

Three-roll bender (Φ50×3.0 mm, min radius R250), the 14-station greenhouse tube bender, and the exhaust band clamp line — roller materials, powers and holding accuracy.

The steel 1600 mm class line and the aluminium 2600 mm class line — coil range, cutting length, +/-0.5 mm accuracy, and why the leveller, not the shear, decides the result.
