AUSTRALIAN COATINGS MANUFACTURER
Protecting the structures
that connect us.
Protective coating systems for infrastructure. From exposed structural steel to demanding wet-service assets, specify protection around the conditions that matter.
INFRASTRUCTURE
Protection starts with
the right specification.
Every structure has its own exposure, access and maintenance requirements. ALKA manufactures protective coatings for steel and selected concrete applications, supported by practical system guidance.
Explore solutions by industry, compare coating builds and work with our technical team to confirm the substrate, preparation, film thickness and finish for your application.

Water & wastewater
Barrier and chemical-lining options for pump stations, treatment assets, bunds and process areas, selected for the actual service.
Explore solutions →MATCH THE SYSTEM TO THE SERVICE
From atmospheric protection
to specialist linings.
Select a coordinated primer, barrier and finish rather than a product in isolation. Our system library covers external steel, routine maintenance, coastal atmosphere and wet or chemical service.
Premium External
Premium corrosion protection combined with a UV-stable, colour-retentive finish
View system →Maintenance / Refurbishment
Reduces preparation demands and supports practical maintenance programs
View system →Marine Atmospheric
Premium salt-laden atmospheric protection with a durable UV-stable finish
View system →Glass-Flake Barrier Lining
High-build glass-flake barrier delivers strong resistance to permeation, wet service and abrasion
View system →UNDERSTAND THE BUILD
Each layer has a purpose.
A complete coating system combines preparation, corrosion protection, barrier performance and the required surface finish.
This external steel example brings together a zinc-rich epoxy primer, high-build epoxy and polyurethane topcoat. Wet-service, chemical and maintenance applications use different builds.
