Construction
Architects and building owners are increasingly turning to prepainted metal to meet their design vision for both commercial and residential installations. Prepainted metal’s ability to be formed into almost any shape, excellent resistance to weathering for superior longevity, infinite aesthetic color and texture options, and positive environmental benefits, make it a perfect choice for both interior and exterior construction applications.

Roofing
Prepainted metal roof panels are produced in a wide array of shapes by a large selection of manufacturers to meet any design need. Metal roofing profiles are generally separated into two major categories including standing seam and formed shapes. Standing seam roofing panels are roll formed into almost any length and are available in both exposed and hidden fastener systems. Formed shape prepainted roofing systems transforms metal roofing into profiles that look like clay tile, slate, cedar shakes, shingles, and more. In addition to beauty, longevity, and functionality, prepainted metal is available in “cool” infrared reflective pigment technology. This technology saves energy (and money) on cooling by helping reduce a building’s interior temperature.

Walling
Prepainted metal is a perfect choice for interior and exterior wall panels. Metal wall panels are available in a large number of differing profiles in ribbed, insulated (foamed), composite, and architectural shallow flat styles.

Soffit and Facia
Soffit, facia, and an assortment of other building trim parts are produced out of prepainted metal helping a home or business streamline its looks while protecting the underlying structure.

Rainware
Prepainted metal’s ability to be formed into almost any contortion of shapes imaginable make it a popular choice for manufacturing gutters and downspouts, as well as a wide assortment of parts needed for rainware installations. Another rising use of prepainted metal is for various leaf and debris prevention systems that have recently been introduced to the market.

Garage and Entry Doors
Prepainted metal’s ability to be stamped into deeply drawn and detailed shapes, resistance to weathering, economical benefits, and environmental advantages makes it a perfect fit for Garage and Entry door manufacturers.

Storage Units
Self storage units are being constructed at a rapid pace across the United States as the need for homeowners and businesses to store materials off-site increases. Prepainted metal is used for almost every part of these structures including roofing, walling, rainware, and even the roll-up doors.

Interiors
Prepainted metal is used extensively in interior building design. Sometimes its use is subtle and becomes an integral part of the design, and sometimes the metal itself is the major focus of the design. Ceiling tiles, back splashes, ceiling grids, wall panels, wainscoting, and column surrounds are some of the uses of prepainted metal for interiors.

Transportation
The transportation goods industry encompasses several different product types, all of which have or can benefit from the use of prepainted metals by not only streamlining the manufacturing process, but by drastically reducing production costs.

Automotive
By using pre-primed substrates in automotive production, the use of certain in-process materials as well as wasteful primer oversprays are eliminated.

Motorcycles
Pre-painted dry lubricants not only eradicate material costs, but also several steps in the production process as they afford the manufacturer the ability to stamp out gas tanks without the use of wet oils.

Tractor Trailers
Zinc rich weldable primers are already cleaned, free of oil, and ready for further production and post painting.

Trailer Van Panels
The Truck Trailer industry is successfully using prepainted polyester and acrylic coatings which can be silk screened and perform beautifully over the road for many, many years.
Appliances
Appliance manufacturers are turning to prepainted coil in increasing numbers for several compelling reasons:
• Lower cost solution
• More consistent product
• Team approach to innovation and problem-solving (manufacturer/coater/coating supplier)
Many types of appliances utilize coil coated metal including:
Laundry
Control panels have long been prepainted, but those new brightly colored washers, dryers, and pedestals are prepainted too!

Refrigeration
Refrigerator wrappers, doors, and interiors are often made using prepainted metal. Many coil coaters even emboss metal coils after painting, adding a unique look to refrigerators and freezers.

HVAC
For the HVAC industry, the use of prepainted coils means not only a better product appearance, but the benefits of higher product quality and performance, increased productivity, and numerous economic advantages through cost eliminations. The coil coating process has been a proven method of applying high performance coatings over various metal substrates for many decades because the coils are uniformly cleaned, pretreated, and painted as a flat surface ensuring a secure bond to the metal. For HVAC, the benefits include:
• Better Product Appearance
• Higher Product Quality and Performance
• Increase in Productivity
• Cost Eliminations
Furniture

Antimicrobial coatings also provide protection from mold, mildew, and other microbes when used in coil coated products.
Prepainted metal is used in a variety of office furniture products; including shelving, filing cabinets, desks and storage units. Prepainted metal allows the designer to choose a specific finish for an item and is used when cost-effectiveness is a key issue and high-quality aesthetics are important. Prepainted metal allows for two sides to be painted different colors simultaneously. Thus, allowing a cabinet drawer to be colorful outside, and gray inside; or a shelving unit to have contrasting colors on the internal and external parts.

Commercially, prepainted metal is also used in supermarket shelving, benches, counter-tops, and other point-of-purchase displays. Plus, the number one choice of lighting manufacturers is prepainted material painted with high reflectance white coatings.
Other Goods
Manufacturers of a wide variety of metal products utilize prepainted aluminum and steel, using the highly efficient coil coating process, to make consumer, industrial, and commercial products. Manufacturers benefit from using prepainted metal because the coated coils arrive ready to fabricate into parts, are consistent in quality, appearance or functionality. By eliminating the need for a costly in-house paint shop, manufacturers skip meeting stringent EPA regulations and production bottlenecks with prepainted metal. Manufacturers can reduce production costs, save time and hassles by using coil coated metal that is made to their unique specification and performance needs.

Some additional industries that utilize prepainted metal are:

Container
Manufacturers of metal cans use clear, white and gold coatings for the can ends. Container manufacturers use FDA compliant coatings for food products to provide a barrier between the contents and the inside of the metal cans as well as preventing the outside of the metal cans from rusting.

Lighting Fixtures
Highly reflective white coatings are applied to light gauge metal, via the coil coating process, for manufacturers to fabricate into light fixtures.

Electrical Cabinets
Manufacturers of industrial and residential electric cabinets, as well as cable boxes and tool boxes all use metal that has been painted by a coil coater. Weldable, conductive or decorative coatings are applied to the metal to provide corrosion resistance, functionality or an attractive appearance.

And many other industries and end uses...including yours!

Design – Prepainted metal is versatile and can be used almost everywhere – on building exteriors and interiors, appliances, HVAC, furniture, automotive, etc. It is functional and durable, and can be combined with high-performance paint systems in an unlimited spectrum of colors and an array of properties. Designs can be eye-appealing - simple or complex, without affecting long-term durability, corrosion and mar resistance properties, and functionality. Prepainted metal can be formed into almost any shape, provides excellent resistance to weathering for superior longevity, and offers a wide array of texture options. Prepainted metal can be made to look like any material, including wood, slate and asphalt.

Environmental Friendly / Sustainability – The coil coating process itself is considered the most environmentally responsible method to apply paint to steel and aluminum substrates.

• 98% VOC Capture Coil coating is a highly efficient "closed loop" process, meaning that the coating curing ovens burn the harmful VOCs, using them as fuel, saving energy, and eliminating pollutants. Coil coating achieves at least a 98% rate of capture and destruction efficiency, eliminating toxic air pollutants that would otherwise be released into the air.

• Exceeds EPA Standards The coil coating industry is subject to the highest EPA standards and meets and exceeds these standards.
• Recyclable & Recycled -- Aluminum and steel can be completely recycled. Even after multiple times of recycling, they retain their original mechanical properties. Nearly all of the prepainted metal that is used in buildings is collected and recycled after they have reached their in-service lifetime (usually 50 years or more). Recycling helps to reduce landfill waste and to conserve natural resources.

• Longevity of Products – The coating systems used for prepainted metal provide a waterproof and corrosion-resistant barrier that extends the life of a metal substrate. Coil coated metal used for building products provides unrivaled long-term performance. This performance results from the user’s ability to choose materials that meet the needs of the building in the environment in which it is placed. An appropriate combination of metal substrate, pretreatment, primer, and topcoat are available for any set of environmental conditions.

• Energy Efficiency – Prepainted metal can meet all the requirements of the most stringent energy codes. Even dark colors are able to satisfy the solar reflectance requirements that are common in today’s building codes. Using prepainted metal helps to earn LEED credits and meeting Energy Star requirements.

Cost-Effective Solution – Prepainted metal is a cost-effective solution when you consider the many benefits it offers through long-term performance, low maintenance, and available tax credits.
