The right surface for every application

MACO uses seven different surface processing technologies in its in-house production. This means we offer the widest range of surfaces produced in-house in the industry. Our surface processing technologies include: extremely corrosion-resistant TRICOAT-PLUS, silver-look (electro-plating), RUSTICO-PREMIUM-PLUS (powder coating), anodizing, wet varnishing, vacuum deposition and PVC coating.

MACO Surface Technology

Optimum corrosion protection


    Top protection against salts, acids and alkalis, aggressive cleaning agents and builder's dust – with guaranteed corrosion protection in sophisticated white aluminium. The tested quality far exceeds the requirements of Class 5 in accordance with EN 1670:2008. There's no contender when it comes to rust: use TRICOAT-PLUS hardware in coastal regions, industrially congested areas, indoor swimming pools and livestock stables; as well as when processing highly tannic types of timber, such as oak or acetylated Accoya®. Since a delivery date of April 1, 2012, we have been offering a 15-year guarantee on TRICOAT-PLUS, and a 10-year guarantee for use on Accoya® and oak wood. The optional surface finish is available for MULTI-MATIC turn-only and turn&tilt hardware, PROTECT door locks, RAIL-SYSTEMS lift&slide hardware and ESPAGS espagnolettes, completed with specially-coated screws.

Questions and answers

about surface finishes

  • What is corrosion?

    Corrosion is a process in which metallic materials are attacked and destroyed by chemical or electrochemical reactions. This means that the hardware would rust without corrosion protection. It is triggered by substances in the environment, for example in salty sea air, in oak wood containing tannic acid, in aggressive cleaning agents and even in builder's dust.

  • Materials processed by MACO

    We use steel, ZAMAK, aluminium and PVC in the production of hardware. The final surface treatment defines the appearance of the hardware components in terms of colour and surface texture. The hardware is reliably protected against corrosion.

  • Surface processing technologies

    In our in-house production we use seven different surface processing technologies: TRICOAT-PLUS, silver-look (electro-plating), RUSTICO-PREMIUM-PLUS (powder coating), anodizing, wet varnishing, vacuum deposition and PVC coating.

  • Why do I need surface protection?

    The coating protects the base material against environmental impacts and signs of wear, offers decorative design options and improves technical properties such as slip and wear characteristics.
