Materials & Surfaces
Each surface design gives every building its individual character.
Kasso panels are available in a large variety of finishes and materials, which provides designers and architects the freedom to create a diverse range of patterns and designs.
Preferences of material choices and surface finishes are mainly based on the visual expectation and the site conditions to determine the final appearance and increase the lifespan&performance of a building. Wide range of material is offered including aluminum, stainless steel, cor-ten steel, copper to titanium zinc, composite aluminium and can be supplied in many surface options such as powder coating, anodizing, satin, galvanization, pre-aging to fulfil project’s requirement.
Guide to Alloys
Kasso offers various products in a wide range of materials. The properties of the most popular materials are listed.
As carbon steel is not resistant to corrosion, it must be painted or galvanized for protection. The raw material is processed by either cold rolling or hot rolling, both of which affect the properties of the product. Cold rolling provides better surface conditions with lower tolerances. Recommended alloys: ST37, ST50 Quality.
Aluminum is durable, elastic, and stainresistant. It allows for a variety of surface treatments that provide different colors, patterns, and textures. It is 100% recyclable and environmentally friendly, as it doesn’t lose
its elemental properties. With a wide variety of alloys, aluminum is preferred for its weight advantage. Recommended alloys: 1050, 3003, 5005.
These are steel alloys with added copper, chromium, nickel, and phosphorus. When exposed to the atmosphere, Corten steel
forms a permanent layer of rust, which makes the material resistant to weather conditions. Corten steel is preferred by architects, designers, and artists for its unique texture and color.
Stainless steel forms a coating that is protective under normal conditions and self-renewing when damaged. It is resistant to corrosion, wear, and all types of weather conditions. Stainless steel has a distinctive appearance and high level of durability that allows it to be used as thin panels. Recommended alloys: 304, 316,
316L, 430 Quality.
Zinc alloys (99.995% zinc + 0.003% titanium) are more durable than brittle zinc. The patina formed on the surface reduces its interaction with the elements in the air, protecting the surface from weather conditions. Its malleable
texture makes it a popular choice for curved surfaces. Recommended alloys: C28000, C22000.
Noted for its bright red hue, copper is lightweight and durable. The rich aging process of the material gives it a variety of unique and authentic appearances depending on the surrounding temperature and humidity levels. Copper not only conducts heat and electric current very well, but it also boasts antimicrobial properties. Recommended quality class: C11000, C12500 Quality.
With an appearance that’s similar to shiny gold, brass is resistant to corrosion and wear. This malleable material is also a conductor.
The composite panels consisting of a polyethylene or mineral filled core between two aluminum cladding sheets.
Pre-galvanizing is also known as the mill galvanizing. The advantage of this method is that coils of steel sheet can be rapidly galvanized on a large scale with a uniform coating and provides corrosion resistance.
Surface treatments provide unlimited surface finishing options for metal panels and contribute to increasing performance and product life. The most preferred surface treatments are listed.
Electrostatic Powder Coating
This process involves the coating of metals in powdered paint using either robots or manual guns under a static current of 80 kV, then curing them in a 180-200°C oven. Electrostatic powder coating offers unlimited color options for project-specific applications. Depending on the paint class preferred, it maintains its durability for up to 30 years.
This is the anodic oxidation process of aluminum metal parts in a chemical solution using a direct current of electricity. This process creates a micron-thick layer on the surface of the aluminum, which increases the material’s resistance to corrosion. Anodized finishes can be applied matte, glossy, or as a satin, with the most popular finish options being natural aluminum, bronze, and gold.
Metal alloys whose surfaces are frequently given a satin finish include stainless steel, aluminum, and brass. The patterns formed on the metal’s surface based on the depth and method of treatment give the metal a homogenous and decorative appearance as well as allowing for easy long-term maintenance.
Wood Effect Transfer
This process involves the application of a hydrographic film to the surface, which allows for pretreatment and gives the surface a wood grain effect in the desired texture and color. In addition to boosting the durability of metal surfaces, this coating is also used for decorative purposes.
Hot- dip Galvanize
This coating process involves the dipping of steel material into a molten zinc bath at a temperature of 449°C to form a protective layer of zinc-iron alloys on the steel surface, thus increasing its corrosion resistance.
Super Mirror Finish
A mirror finish is a highly reflective, shiny, smooth finish with a scratch free appearance, achieved mechanically by using a progressive series of abrasives and polishing compounds.This particular finish is most often applied to stainless steel for use in architecture and design projects, also known as a #8 finish.
This protective chemical can be applied in a matte or glossy finish. Although there are both wet and powdered varnishes available, the most frequently used is the powdered version. It is used to form a protective layer on metals or painted metal surfaces with a static gun.
This is the process of plating steel with a layer of zinc via electrolysis. By forming a thin coating, electrogalvanization creates a highly corrosion-resistant surface.
Metals tend to physically transform over time due to natural environmental conditions. The texture and color of the metal surface changes with an oxide layer forming on it in the initial stages. Soon this layer converts to a hydroxide layer. Later this hydroxide layer combines with other elements in the atmosphere and finally the metal surface gains a stable mineral composition that is very resistant to any further alteration. This weathering or aging process can be applied to cor-ten steel, copper and copper alloys.
