Dear customers and partners,

At Chapel, we have always taken pride in offering cylinders that combine strength, sustainability and compliance with environmental standards. With our range of telescopic cylinders, we are setting the competitive standard.

And here’s why.

Robust and long-lasting

Our cylinders are designed with parts machined from solid, ensuring optimum mechanical strength. This design ensures a working life in exceeding 20 years, far beyond market standards.

As proof of this, some of our customers are replacing the seals on cylinders that are over 30 years old!

Our treatment: a sustainable, high-performance solution

We have opted for nitrocarburizing and post-oxidation to ensure maximum protection and performance:

• Nitrocarburizing (standard on all our telescopic parts): excellent resistance to wear and friction, as well as classic corrosion resistance.
• Post-oxidation: optional extra layer offering superior corrosion protection (x3 compared with conventional resistance).

Our treatment modifies the physical structure of the steel itself, making it much more resistant to impact and extending the lifetime of the corrosion protection, unlike coating processes such as chrome plating, zinc plating and painting.

A more eco-friendly choice.

Post-oxidation and nitrocarburizing offer major ecological advantages:

• Toxicology, ecotoxicology: nitrided elements do not contain hexavalent chromium (Cr6), which is becoming increasingly regulated.

• Eco-friendly process: our treatment processes (gas or salt bath) generate few or no waste products, and waste can be fully recycled to produce new reagents with virtually no impact on the environment.

• In comparison with chrome: traditional chromium plating offers variable resistance (96h/120h in class 9 BS for the most common applications, and between 24h and 1000h depending on production methods).               Post-oxidation is therefore a high-performance, eco-friendly alternative.

French production and European sourcing

• Our cylinders are manufactured in France using rigorous European sourcing, guaranteeing an optimised carbon footprint.

• We offer a wide range of fittings (rod ends, spherical plain bearings, trunnions) and supply fittings to suit all your needs.
