“New Energy”

“SUNNIK” means “NEW ENERGY” - representing the power of our commitment to providing the most hygienic, cost-effective, easy-to-install, and durable water storage tanks available.

Steelworks Engineering SDN BHD, founded in 1984, named its first pressed steel sectional water tank “SUNNIK.” Since then, this new energy has continued driving us to excellence and innovation in technology, customization, installation, extending tank service life, and, above all, customer service and support.

Over 35 years, we’ve built a reputation for best-in-class water containment systems - serving a complete range of needs from the world’s tallest skyscrapers like Burj Khalifa and The Petronas Twin Towers to the domestic water storage system for a town in Ghana. With our tanks in use in over 42 countries, we’re a global leader in water containment.

Our modular panel tanks - secure, flexible, reliable

Modular panel tanks have no equal for ease and flexibility - simple to ship and assemble in even the remotest locations. The same modular system lets you build a two-square-meter tank for a single household or a 2,000-square-meter tank to supply an entire town. They're also cost-effective because you choose the panel material according to your needs and budget.

We use cutting-edge design and fabrication methods to ensure each panel's quality and consistency, including robotic welding, laser cutting, and sheet molding compound (SMC) with 1000-metric-ton hot-pressed compression. We seek out and adopt the latest technologies from leading manufacturers in Britain, Japan, and international joint ventures. Sunnik was the first in the region to provide hydraulically pressed sectional steel tank covers that support walking, epoxy-coated sectional panel tanks, SS316, and SS444 stainless steel panel tanks.

All our tank systems are earthquake tested up to 1.5g. Sunnik's fiber-reinforced polymer (FRP) or glass fiber-reinforced polymer (GRP) panel tanks meet the applicable British Standards Institute quality standard (BS EN 13280:2001) and are built with a factor of safety (FoS) of six times the maximum anticipated loads, while other brands are made with and FoS of only four.

Staying on the leading edge to maximize the performance of every tank panel is just part of what we do to ensure our water storage solutions are second-to-none.
