Modular steel deck wash bays are engineered for Australian industries needing a relocatable solution without civil works. These wash bays use a hot-dip galvanised steel deck built to withstand large equipment and vehicle loads. They suit heavy equipment and trucks used in mining, construction, transport, and government. Because the system is above ground, the wash bay can go anywhere water containment is required, even where space is tight or the site is unroofed.

These modular solutions work best on remote mining operations where quick setup and compliant cleaning are critical. Each deck module can accept high pressure cleaning systems, wheel cleaning, and water treatment attachments with oil water separators, silt screens, pumps, and pits. Modular washpad options meet EPA wastewater containment standards, helping industry operations avoid shutdowns. If you need engineered load capacity, these wash bays manage 1T to over 100T per axle, ensuring compliant truck and heavy equipment use.

Modular steel wash bays also streamline trade waste approval. A compliant modular wash bay can pair with wheel wash systems and wastewater treatment systems, including oil water separator units, grease control, solids handling, and settlement tanks for full environmental protection. They work with vacuum pumps and pressure wash cabinets, pumps, chemical-rated bunding, and bunded drum storage. Fibreglass drums, wheel wash ramps, and spill barrier curtains integrate easily.

Key benefits:

Even in Perth or remote WA, portable modular decks arrive ready for quick site setup. Fitting the deck to your specific cleaning needs ensures the right product for heavy-duty wash bay operations.

Ensuring long-term compliance is simple with modular steel deck wash bays designed for real-world conditions. With straightforward maintenance, wheel wash systems, and integrated oil water separators, your team can efficiently manage vehicle, wheel, and equipment washing while protecting the environment. Whether you need temporary or permanent operation, these rugged, relocatable systems support reliable cleaning performance across changing sites.

Chemical-proof fiberglass pads protect against chemicals, grease, fuel, waste oil, gas runoff, and abrasive cleaning processes. They support light fleet operations, automotive cleaning shops, commercial businesses, compact machinery, and small motorcycle service areas. The pad system helps control spill hazards by containing wastewater in a sealed fiberglass structure. Unlike concrete, fiberglass does not react with chemicals commonly used across industries.

These systems are completely above ground and often combine with drum storage cabinets, hot water pressure wash equipment, and emergency shower areas. Many pads accept modular trade waste systems and external pit plumbing. In high-risk industries such as chemical processing and government fleet operations, fiberglass pads ensure environmental containment and compliance with minimum risk. Operators can back vehicles into the wash bay, wash quickly, and divert wastewater to a tank or treatment system with oil water separators.

They are compliant with Australian EPA guidelines for stormwater protection. Because they are relocatable, they follow mining and construction projects. The pads resist corrosion caused by wash chemicals, solvents, lubricants, grease, and heavy dirt. They are engineered to standard load ratings suitable for truck wheels and various vehicles.

Key features:

Fiberglass wash bays suit a commercial fleet wash system needing minimal maintenance, with hot-dip coated steel accessories available for high load upgrade use. These products are made to meet Australian standards for wash area containment and meet environmental compliance. Contact our team at WashBay HQ today!

Fully enclosed portable wash bays protect the environment by controlling water, air, and spill exposure. These wash bays use heavy-duty enclosures, curtains, and bunding to keep wash activity inside the system. They are especially suitable for industries handling contaminated wheels or heavy trucks that require compliant cleaning before site exit. Mining, automotive, government, and equipment hire fleets get operational flexibility with strong containment.

Water is channelled into oil water separators, and solids are captured before discharge. Closed units can include washpad bunding, pump tanks, and rainwater diversion. Because the structure is enclosed, grease, solids, chemical residues, and airborne spray remain within the bay. These wash bays are ideal for unroofed sites requiring EPA-compliant wastewater control.

Heavy machinery cleaning and wheel washing demands a wash bay able to handle large vehicle load ratings. Many enclosed systems use modular layout options for ground setup, avoiding civil concrete pits and allowing customisable placement. The wash bay can reposition between sites when operations shift. Access can be fitted with spill curtains, bund barriers, and screens to prevent wash spray and ensure operator safety.

Fast approvals are possible because the system is relocatable and engineered to standard Australian pit and wash requirements. They deliver flexible options for industry operations where weather control and treatment integration are necessary.

Fully enclosed portable wash bays give operators confidence that every wheel wash is contained and compliant, even on challenging sites. Their modular layouts support fast mobilisation, controlled discharge, and dependable treatment performance. When you’re ready to tailor an enclosed system to your fleet or facility, contact our team for guidance on the best configuration to keep operations efficient and environmentally responsible.

Closed-loop water systems recycle wash water for continuous cleaning, cutting operating costs while meeting compliance. These systems include separators, pumps, tanks, filters, grease control, and solids capture. Water moves through treatment processes, including oil water separator modules, settlement pits, and chemical polishing. Recycled water is reused for washing applications, reducing demand on external supplies like rainwater tanks or council connections.

A recycling system helps mining fleets reduce waste and improve environmental performance. A recycling bay reduces discharge volume, helping meet national EPA requirements. Many systems require no sewer connection, making them suitable for remote sites where septic capability is limited. The process permits the cleaning of heavy trucks and large equipment while reusing water repeatedly. They can also handle motorcycles, small vehicle fleets, and mixed automotive equipment.

Because water supply is a high-cost part of cleaning operations, closed-loop designs help achieve long-term budget control. They can deliver 50-80 percent water savings. Water that remains is stored for further treatment or to pump off-site. Treatment tanks capture solids and improve separator efficiency.

Closed-loop solutions are made in Australia for tough industries, engineered to survive harsh conditions. Compliant products help meet trade waste requirements quickly.

Rapid-deploy mat bays deliver the fastest way to get operations compliant. These bays ship rolled, deploy on level ground, and capture wash water instantly. They are ideal for temporary works, lease areas, construction pads, or seasonal sites. Their design features a flexible washpad fitted with bunded edges that prevent wash water from escaping.

Because they are easy to handle, installation requires no civil works. Operators simply roll out the mat, position a pump, and begin cleaning. They suit light automotive equipment, small fleet operators, motorcycle cleaning tasks, and similar applications. The mats are compatible with pumps to transfer wastewater to a tank or portable separator system.

These mats work well in fast-moving operations. They can accept solids included in wash runoff and handle grease or chemical residue. Spill response is simple: bunding prevents leakage, reducing environmental risks. They are convenient for emergency operations needing immediate containment.

Rapid mats also deliver excellent value for business because they reduce system downtime. The bay can shift back and forth between locations as needed, supporting flexible projects. Standard sizes are available, but customisable bays fit unique site needs. They suit short-term washpad applications in commercial and government work.

Portable wash bays keep heavy industry compliant without civil approvals. Council delays can take six months, while relocatable modular bays can be operational in days. Approvals always take too long unless you do this: select an engineered above-ground system that meets discharge standards without excavation. Many fleets need full environmental containment without building ground slabs or pits.

Portable systems are especially useful when operations shift. Many fleets expand to new locations, and the bay can follow. Relocatable solutions reduce sunk cost and provide full control over load performance. Australian operators in mining, transport, defence, equipment hire, and construction benefit from compliant, ready, hot-dip steel options that reduce maintenance requirements. Bunded decks, pits, and oil separator tanks allow easy solids removal, drum storage, and grease control.

These systems integrate pumps, tanks, curtains, and storage bins to deliver cleaning capability anywhere. Whether on a small automotive space or a large heavy-duty mining depot, the bay design can match the application. Operations teams can order online, request national delivery, and get sales assistance with compliance.
