Why is choosing the color of galvanized sheet an engineering decision?
The color of the galvanized sheet surface directly affects the amount of solar heat absorption and reflection (SRI index). Choosing the wrong color for the roof of a large shed can increase the cost of cooling the space in the summer by 20%. On the other hand, the durability of color pigments against intense sunlight and acid rain requires a standard factory coating so that they do not crack and peel during the forming of galvanized sheet.
Specialized review of the use of various galvanized sheet colors
Galvanized sheet color palette
1. White galvanized sheet (RAL code 9016 / 9010); ultimate light reflection and energy efficiency
White is the most widely used color in the metal structures industry.
- Technical feature: the highest solar light reflection coefficient and the lowest heat absorption.
- Applications: Roof covering of industrial sheds, warehouses, cleanrooms, food and pharmaceutical industries, and the inner surface of ceiling and wall sandwich panels.
- Advantage: Significantly reduces the cooling load of the structure in hot seasons and creates natural lighting in the factory environment.
2. Gray and gray galvanized sheet (RAL code 7016 / 7035); a modern and neutral choice
- Gray shades (from silver and ivory to charcoal gray or anthracite) are the symbol of contemporary industrial architecture.
- Technical feature: High resistance to showing pollution and excellent harmony with concrete, glass and wood materials.
- Applications: Facade of modern office-commercial buildings, high-tech sheds and facade flashings.
3. Black galvanized sheet (RAL code 9005); a luxurious and special trend of contemporary architecture
Matte and glossy black sheet is one of the special and very distinctive colors on the market that has a stunning visual appeal.
- Technical feature: Higher heat absorption, requires high-quality kiln painting and a scratch-free production line.
- Applications: An excellent choice for covering the roof and walls of prefabricated Swiss villas (A-Frame), facades of luxury eco-tourism projects, modular cafes and decorative flashings on the edges of structures.
Sabat Sanat's distinction: Due to its high sensitivity to scratches, the black sheet is formed using fully polished molds of modern machinery to deliver a completely uniform and damage-free surface to the customer.
4. Blue and navy galvanized sheet (RAL code 5015 / 5010); a symbol of industrial identity and authenticity
Carbon blue and navy are the flagship colors of industrial towns and large factories in the country.
- Technical feature: Excellent optical stability and conveying a sense of security, stability and industrial trust.
- Applications: Roof and body of production sheds, covering of workshop and office buildings, aircraft hangars and ports.
5. Red and brown galvanized sheet metal (RAL code 3000 / 8004); warm, classic and eye-catching
- Technical feature: High visual visibility index and reminiscent of traditional pottery in pottery design forms.
- Applications: Sloping roofs of villas in the north of the country, tourist resorts, gas stations and warning/safety signs.
6. Green and yellow galvanized sheet metal (RAL code 6005 / 1021); nature, distinction and special use
- Green: harmony with vegetation and nature; ideal for industrial greenhouses, sports halls and parks.
- Yellow: eye-catching color; ideal for sports halls, logistics sheds and elements with safety protocols.

Why entrust colored sheet forming to Sabat Sanat?
The difference between a standard colored sheet and a low-quality sheet is determined at the forming stage. If worn-out machinery is used, the paint will develop microcracks in the bending lines and rust after the first rain.
Sabat Sanat, using advanced roll forming lines, guarantees the following benefits:
- Cold forming without damage to the paint: complete preservation of the zinc coating and the oven paint even in the most complex forms.
- Providing all color and special codes: from standard white to luxurious matte black and metallic navy.
- Integrated complementary services: simultaneous production of sheets, flashings, edges and edges of the same color for 100% sealing of the structure.
- Customized longitudinal cutting: Precise cutting without pleats according to the dimensions of your project plan (minimizing waste).
