Bulkhead – Sea Docks
- Performed restoration and preservation work on bulkhead surfaces exhibiting heavy corrosion and rust accumulation. The work scope included mechanical surface preparation using blasting methods, pneumatic air tools, including needle guns and chipping equipment, to remove loose scale, rust, deteriorated coatings, and surface contaminants. Following mechanical cleaning, all prepared surfaces to remove dust, oils, and residual contaminants.
- A saltwater treatment solution and approved rust-inhibiting chemical is then applied to stabilize and contain any remaining corrosion within inaccessible surface pits. Once the treated surfaces were properly prepared and cured, a protective coating system was applied consisting of primer as the base coat, followed by black topcoat (or project-specified equivalent) to provide long-term corrosion protection and durability in a marine environment.
- All work is performed in accordance with applicable surface preparation, coating application, and marine maintenance standards to extend the life of the bulkhead structure and prevent further corrosion-related deterioration.

Fire Barriers / Fire Door
Our team provides complete supply and installation of UL-rated fire barrier partition systems designed to meet commercial and industrial fire protection requirements. The scope includes installation of 1 hour, 2 hour, and 3 hour rate systems under ANSI/UL 263. All components are installed to create a durable, code-compliant 2-hour firewall assembly, ensuring enhanced fire resistance, structural integrity, and long-term performance.
Fire Rated Thermal insulation
- A dual-purpose material that prevents heat transfer while also resisting, containing, or slowing the spread of flames during a fire.
HVAC fire damper insulation
- Specialized, high-temperature, fire-resistant insulation materials applied to the exterior sleeves of fire dampers. Its primary purpose is to protect the damper components from excessive heat transfer during fire, preventing premature failure and ensuring the damper can legally seal off fire-rated walls or floors.

Pipe restoration
- We provide professional pipe restoration services for industrial, marine, and energy-sector facilities. Our process includes removing rust, deteriorated coatings, and surface contaminants through mechanical surface preparation, followed by thorough cleaning and the application of corrosion-resistant coatings and protective paint systems. By restoring and protecting piping systems from corrosion, moisture, chemical exposure, and environmental damage, we help extend service life, improve reliability, reduce maintenance costs, and maintain the integrity of critical infrastructure.
Tank paint
- The project involves complete surface preparation, corrosion treatment, and recoating of above-ground storage tanks used for the containment of any liquid commodities commonly handled within industrial energy services operations. Our process begins with the removal of deteriorated paint, rust, and surface contaminants through grinding and mechanical surface preparation to ensure a solid foundation for new coatings. Once surface preparation is complete, tanks are cleaned using lacquer thinner and pressure washed to remove dirt, debris, oils, and other contaminants. Rust-prevention coating is then applied to help protect the steel substrate and prevent future corrosion. For long-term durability, we apply a high-performance coating system primer followed by a topcoat. This coating system provides excellent protection against weather, moisture, corrosion, and everyday wear while restoring the tank's appearance and extending its service life. Our tank restoration services help customers protect valuable assets, reduce maintenance costs, and maintain safe, professional-looking storage facilities.
Complete new constructions – metal building
- New construction of a metal building involves building a structure from the ground up using prefabricated steel components. It begins with site preparation and pouring a concrete foundation. Afterward, a heavy-duty steel skeleton includes columns, trusses, and purlins. This erected, followed by the installation of metal roofing, exterior sheeting, and insulation
Offshore Marine flooring
- Offshore marine flooring is specialized, high-performance decking engineered to withstand relentless saltwater, heavy machinery, and extreme weather on oil rigs and marine vessels. Essential for survival at sea, it provides life-saving slip resistance, fire-retardant safety compliance, and critical rust protection for a ship's steel structure. The multi-step installation process involves blasting the metal deck clean, applying anti-corrosive primers, pouring sound-dampening underlayment, and sealing the surface with ultra-durable, chemical-resistant resins or heavy-duty marine vinyl.
Offshore Marine Galley Hood Cleaning
- is the specialized deep cleaning of commercial kitchen exhaust systems offshore oil platforms. It removes flammable grease buildup from hoods, ductwork, and fans to prevent fires, ensure regulatory compliance with the US Coast Guard and NFPA 96 codes, and improve onboard hygiene

Offshore Marine Crane Cab Restoration
- Crane operators working in offshore environments depend on safe, functional, and reliable cab systems every day. Constant exposure to saltwater, wind, vibration, humidity, and harsh weather conditions can gradually deteriorate crane cabins, affecting both operator comfort and equipment performance. Over time, corrosion, worn components, and outdated systems can reduce efficiency and increase maintenance concerns.
Offshore Marine Plumbing – Demo & Re-Installation with Marine Grade Materials
- Plumbing systems aboard marine vessels and offshore facilities face conditions that land-based systems rarely encounter. Constant exposure to saltwater, vibration, humidity, temperature changes, and confined operating environments can gradually wear down piping infrastructure over time. When aging systems begin to deteriorate, replacement often becomes the safest and most reliable solution.
Offshore Marine Living Quarters Complete Remodeling
