Tubing manufacturer with ISO 14001-certified environmental management
Delmàs has its environmental management system certified to ISO 14001, and we manufacture with 100% renewable energy since 2006, with two photovoltaic self-consumption installations at the plant.

What ISO 14001 is
ISO 14001 is the reference international standard for environmental management systems (EMS). It attests that the organisation systematically identifies, controls and improves the environmental impact of its activity —energy use, waste, emissions— under independent external audit.
What it attests
An ISO 14001 certification attests that the company:
- Identifies its environmental aspects and complies with the applicable law.
- Sets environmental improvement objectives and reviews them.
- Manages waste, consumption and emissions with defined procedures.
- Undergoes periodic external audits.
What it means for you
More and more tenders, specifications and supply chains require environmental criteria of their suppliers. A manufacturer with ISO 14001 —and with demonstrable renewable energy— lets you meet those criteria upstream and contribute a real figure to your own carbon footprint and your sustainability reports.
The important nuance: it certifies the company, not the tubing
ISO 14001 certifies Delmàs's environmental management system, not an attribute of the tubing. We avoid any "eco tubing" or "green tubing" message that cannot be demonstrated: what we communicate are verifiable facts —renewable energy since 2006, photovoltaic self-consumption— and an audited environmental system. Rigour, not greenwashing.
Sectors
Environmental criteria carry weight across the board, and especially in tenders and with customers that have sustainability commitments in their supply chain: automotive, contract, design furniture. You can find out more on our Sustainability page.
