K5
OCM's developed K5: Rustic Metal Finishes to provide an innovative, painted solution to the problems commonly associated with natural, weathering sheet metal. K5 offers a full range of PVDF paint options that replicate the appearance of naturally weathering metals, such as steel, copper, and zinc.
While rusted metal has become widely used in architecture, it comes with many dangers and risks. Rusting metals can corrode, leading to leaks. K5's PVDF coating provides lasting protection to the aluminum or steel substrate. Natural rust can drip from roofs and run down walls, staining the surrounding materials and sidewalks. With K5 there is no rust, so there is no staining.

Natural metals can also be unpredictable. Natural metals will age to a variety of colors depending on their environment and atmosphere, making it difficult to achieve the desired results. OCM can precisely replicate K5 colors and can even create custom variations, providing control and predictability. K5 Rustic Metal Finishes have been widely used in commercial, institutional, and residential building applications, including corrugated and standing-seam roofing, wall cladding, column covers, doors, ceiling panels, soffits, and window mullions. K5: Rustic Metal Finishes are processed exclusively on Old Country Millwork’s coil coating line in Los Angeles, California. They can be supplied in coil or flat sheets, both of which can be supplied with removable protective film if required.
The K5: Rustic Metal Finishes coating system is specially designed for roofing and construction projects. It offers excellent UV color stability and high resistance to chalking and fading. These finishes also provide outstanding surface hardness, which significantly enhances scratch and scuff resistance and helps minimize damage during transit and installation. K5: Rustic Metal Finishes are highly resistant to chemicals and are durable products that perform well in severe environments. An advantage of using K5: Rustic Metal Finishes over weathering steel is that it prevents rust runoff or staining on surrounding materials, including driveways and sidewalks. Using K5: Rustic Metal Finishes can also help prevent substrate corrosion and failure.:
K5: Rustic Metal Finishes are ideal for a wide variety of commercial and residential applications, including roofing, building panel, fencing, tubing, and decking. With over 20 unique styles, K5: Rustic Metal Finishes can satisfy a wide range of visual requirements. All of the K5: Rustic Metal Finishes can also be formulated with “Cool Roof” pigmentation to meet Energy Star ® Cool Roof application requirements for IR (inferred reflective) building envelope products, adding to the building’s energy efficiency.

Aluminum Composite Material (ACM) Sheets
Architectural & Designers' Preferred Material
ACM is a versatile panel product consisting of two thin, pre-finished aluminum sheets bonded to a lightweight core (typically polyethylene or a fire-resistant mineral core). This construction results in a durable, lightweight, and highly aesthetic material favored for exterior cladding, custom signage, and complex architectural applications.
Key Properties and Advantages:
-
Durability and Corrosion Resistance
ACM is renowned for its resilience, maintaining integrity even as external coatings age.
-
Lightweight
Significantly lighter than solid aluminum plate, making transport and installation faster and simpler.
-
Aesthetics and Design Flexibility
Available in a vast range of standard colors, textures, and specialty finishes that can convincingly mimic materials like wood or stone.
-
Fabrication Ease
ACM is easily workable—cut, routed, bent, and rolled—allowing for complex curves and intricate shapes.
-
Versatility
The smooth surface is perfect for high-quality digital printing, vinyl graphics, and screen printing.
-
Architectural Cladding
Forms a protective and aesthetic exterior layer for building waterproofing systems.
-
Custom Signage
A preferred substrate due to its printability and ability to be routed for dimensional effects.
-
Art and Design
Highly durable and versatile for various artistic and custom design installations.
