Browse Guides by Topic

Guides are grouped under the topics that matter most to importers, distributors, projects and installers — PPR systems, underfloor heating, brass and valves, sourcing and import, and the standards behind them. New guides publish on a rolling schedule.

III. E-E-A-T From the factory, not a content farm

Why Learn Piping from the People Who Make It

Most piping content online is written to rank, not to inform — thin listicles from marketplaces and content farms that have never welded a joint or shipped a container. Our guides come from a working factory floor.

I.

A real manufacturer, not a trader

PPR, PEX and brass systems plus underfloor heating, manufacturing since 1993 on our own extrusion, injection-moulding and machining lines — one complete system from one source, mixed in a single container. The standards you read here are the ones our own importers and project buyers hold us to.

II.

Certified, not just claimed

ISO 9001:2015, ISO 14001:2015 and ISO 45001:2018 management systems, plus EU CE, Swiss SGS and Russian PT marks — third-party certifications you can verify in the issuing bodies’ own registers rather than take on trust. They are what decide tenders and market entry across Europe, Asia, Africa and beyond. Certificate numbers are available on request.

III.

Written from real sourcing questions

Every guide answers something our own importers, projects and private-label partners actually ask us. When a guide tells you how to spot a real factory, it is not theory — it is how we operate.
