Meeting the demands of an urbanizing world

The percentage of the world’s population living in cities is expected to rise to a staggering 65% by 2025, up from 50% in 2000. As a result, demand for new infrastructure is going up substantially. This includes commercial and residential buildings, industrial sites, energy and transportation infrastructure. At the same time, construction companies must comply with strict environmental and safety regulations while remaining competitive.

Making construction projects easier and safer

Air Liquide has the expertise necessary to tailor fit gas solutions to our customers’ specific requirements, regardless of the construction project. Whether working in dense urban environments or remote areas, we supply gases in a variety of modes and cylinder sizes.

Safe and easy-to-use products

At Air Liquide we know that the safety of employees and contractors is a priority. This requires an extensive understanding of the processes and products consumed. This is how we ensure full compliance with the highest construction quality and safety standards to face zero accident.

Arc welding in particular provides an effective high-performance welding solution for which we offer ARCAL™, our range of ready-to-weld products for all types of welding.

To ensure the utmost in safety for construction workers, both our ARCAL™ and FLAMAL™ gas cylinders are equipped with EXELTOP™, our innovative line of integrated valves and caps to enhance safety and facilitate lean gas handling and management.
