Hoses pressure tested
What we do
One factory, from pellet to pallet.
Extrusion, steel-wire braiding, assembly, pressure testing and packing all happen on the same floor. That is why we can promise a lead time instead of guessing at one.
Heating & Solar Pipe
PE-RT I/II and PEX-a underfloor pipe, plus pre-insulated solar twin pipe cut to your loop length.
Buried Warning & Protection
PE steel-strip warning plates and tape, printed in your language, detectable before the excavator arrives.
OEM / ODM Manufacturing
New mould, new compound, new print — from drawing to mass production with our own tooling shop.
How it is made
Six stages, all under one roof.
01
Incoming inspection
Resin and steel strip checked against the batch certificate before anything is run.
02
Pelletizing & extrusion
Compounding, then continuous extrusion of the inner tube to the wall thickness on the drawing.
03
Steel wire braiding
Braiding or armour winding over the core, tension held constant along the full length.
04
Assembly & crimping
Brass fittings machined in-house, then mechanically crimped — no glue joints anywhere.
05
Pressure test & QC
Every gas hose is pressure tested; dimensions and print checked against the sample.
06
Packing & shipment
Coil, film, carton or pallet — packed for sea freight and labelled to your part numbers.
