Dual-Barrier Weather Defiance (Ultimate Corrosion Control)
While both substrates deliver exceptional rust prevention, our Galvalume (PPGL) formulation offers an even higher threshold of durability. By fusing a premium metallic substrate with a high-adhesion topcoat, we create a robust “Dual-Barrier” system. This double armor effectively neutralizes severe external threats—from tropical monsoon downpours and coastal salt spray to aggressive industrial pollutants—ensuring your projects outlast the competition.
Seamless Fabrication & Structural Efficiency
Engineered with an outstanding strength-to-weight ratio, our prepainted coils reduce overall structural load while maintaining rigid stability. Furthermore, BOMIS’s strict curing processes ensure supreme paint adhesion. Whether your production line involves aggressive roll-forming, deep stamping, or precision cutting, the coating flexes with the steel, guaranteeing zero peeling, flaking, or micro-cracking on the edges.
Architectural Brilliance & Advanced Functional Coatings
Beyond the striking, fade-resistant visual impact of our RAL 5005 Signal Blue, we offer specialized functional upgrades. For highly regulated environments such as cold chain logistics, food processing plants, HVAC systems, and medical facilities, our topcoats can be fortified with advanced silver-ion antimicrobial technology. This specialized coating actively inhibits bacterial and fungal growth, seamlessly merging premium corporate aesthetics with uncompromising hygiene.
Commercial & Industrial Architecture
Applications: Heavy-duty roofing systems, architectural curtain walls for large-scale plants and stadiums, and premium exterior components (billboards, awnings).
The BOMIS Advantage: Engineered to combat the elements. Our high-adhesion paint systems provide exceptional UV resistance and waterproofing, ensuring that massive industrial facades and roofing structures maintain their structural integrity and vibrant colors, even under the stress of relentless sun and severe monsoon rains.
White Goods & Specialized Appliances
Applications: Premium exterior casings for air conditioners, refrigerators, microwaves, and highly regulated medical device enclosures.
The BOMIS Advantage: Delivers a flawless, scratch-resistant finish that elevates the aesthetic value of consumer appliances. For medical or food-processing galvanized steel coils applications, our customized antimicrobial coatings actively inhibit bacterial and fungal growth, meeting the strictest global hygiene standards.
Transportation & Public Infrastructure
Applications: Logistics truck side/roof panels, shipping containers, highway noise barriers, and heavy-duty signboard backings.
The BOMIS Advantage: Built for the long haul. Transportation and public facilities face constant vibration, road debris, and exhaust pollutants. Our PPGI/PPGL coils offer a high-strength substrate combined with a resilient, anti-corrosive finish, significantly reducing lifecycle maintenance costs for municipal projects and logistics fleets


Q: Why is RAL 5005 the preferred color for industrial buildings?
A: RAL 5005 (Signal Blue) boasts extremely high color saturation and visibility, commonly used for corporate identity colors, modern factories, and large stadiums. It not only provides a professional industrial visual effect but also reflects some heat. Combined with BOMIS’ high-quality finish, it maintains its vibrant color for a long time and is resistant to chalking.
Q: Should I choose PPGI or PPGL in coastal or high-humidity environments?
A: We strongly recommend using PPGL (Painted Aluminum Zinc) in these harsh environments. The aluminum zinc substrate (55% aluminum + 43.4% zinc + 1.6% silicon) offers 3-6 times the corrosion resistance of ordinary zinc substrates in coastal salt spray and tropical monsoon climates. Combined with a PVDF (polyvinylidene fluoride) coating, it provides even superior protection.
Q: Can the paint film thickness (Top/Back Paint) be customized?
A: Yes. BOMIS offers highly customized solutions. Standard configurations typically include a 15-25μm topcoat and a 5-10μm backcoat. For higher weather resistance requirements, we can increase the topcoat thickness depending on the engineering environment, or use HDP (high weather-resistant polyester) and PVDF coatings to ensure color stability for 15-20 years.
Q: Does the RAL 5005 coating support complex molding and processing?
A: Absolutely. Our color-coated coils have excellent film adhesion and flexibility (T-Bend test reaches 0T-3T). During corrugated tile pressing, bending, or stamping, the film will not peel, crack, or flake, ensuring excellent rust resistance at the finished edges.
Q: Can BOMIS color-coated coils have antibacterial properties?
A: Yes. For food processing plants, cold chain logistics, or medical facilities, we can add silver ion antibacterial technology to the topcoat. This special functional coating effectively inhibits the growth of bacteria and mold, maintaining the aesthetic appeal of RAL 5005 while meeting stringent hygiene standards.
