Brief Introduction

Matt Textured colour coated steel plate is a hot-dip galvanized alloy steel plate as a substrate, after the surface of continuous roller coating production method, the use of adding special additives to the coil topcoat, after baking to produce like a fishing net-like pattern effect, can be professionally customized according to the customer's requirements of a variety of different sizes, different depths and shades of different colours of the texture pattern.

Coating Structures

Type of coating structure

• 2/1: Coat upper surface twice, lower surface once, bake twice.

• 2/1M: Coat upper and lower surfaces twice, bake once.

• 2/2: Top and bottom surfaces are coated twice each and baked twice.

Usage of different coating structures:

• 2/1: The corrosion resistance and scratch resistance of single layer back coating is poor, but it has good adhesion, mainly used for sandwich panels.It is mainly used for sandwich panels;

• 2/1M: backcoat with good corrosion resistance, scratch resistance and moulding properties, good adhesion, suitable for single-layer compression moulding panels.

• 2/1M: good corrosion resistance, scratch resistance and moulding properties, good adhesion, suitable for single-layer pressboards and sandwich panels.

• 2/2: double-layer backing paint with good corrosion resistance, scratch resistance and processability, mostly used for single-layer pressboards, but with good adhesion.

Most of them are used for single-layer moulding board, but its adhesion is not good, and it is not suitable for sandwich board. 

In cold climates like those in Ukraine and Russia, patterned or textured color-coated steel tiles, such as those with a corrugated or embossed surface, are preferred for several reasons. Here's why these textured products are favored and how they differ from standard color-coated steel tiles:

Why Textured Color-Coated Steel Tiles Are Preferred in Cold Climates

1. Enhanced Durability and Strength:

- Reason: The embossed or textured surface can improve the structural strength of the tiles, making them more resistant to impact and physical stress, which is crucial in areas with heavy snowfall or ice buildup.

- Benefit: This added strength helps prevent damage from falling ice or heavy snow, reducing the need for repairs or replacements.

2. Improved Insulation and Energy Efficiency:

- Reason: The texture of the tiles can help to trap a layer of air between the tile and the substrate, which can act as an insulating barrier.

- Benefit: This improved insulation can enhance the building's thermal efficiency, helping to maintain indoor temperatures and reduce heating costs during cold weather.

3. Reduced Snow and Ice Accumulation:

- Reason: The textured surface can prevent the smooth sliding of snow and ice, which can lead to dangerous icicles or ice dams on flat surfaces.

- Benefit: The pattern can encourage snow and ice to slide off more easily or break apart, reducing the risk of ice buildup and associated damage.

4. Better Aesthetic Integration:

- Reason: Textured tiles can offer a more visually appealing finish that blends better with traditional architectural styles or rural settings.

- Benefit: The aesthetic appeal of the textured surface can be important for maintaining the visual harmony of buildings in certain regions.

Valspar (Sherwin-Williams) PVDF PPGL Introduction 

High-performance coatings for metal building exteriors, such as Fluropon 70% PVDF, have become the industry standard for preserving metal architecture. Qualities such as film integrity, durability, and resistance to UV rays are just a few of the reasons PVDF coatings have risen to the top.

1. Adhesion Quality

PVDF coating systems offer excellent overall adhesion because of the high-quality resins used in the formulas. Resins hold the entire coating system together, ensuring strong adhesion to the substrate and top coat.

2. Film Integrity

Film integrity refers to uniformity in a coating, meaning the coating resists cracking and general defects. PVDF coatings lead the field with superior film integrity due again to the use of high-quality resins. For example, Sherwin-Williams Coil Coatings uses a proprietary mix of resins that allows our 70% PVDF Fluropon coatings to provide excellent film integrity.

3. Abrasion Resistance

Abrasion resistance is important not only on finished metal building products, but also while metal panels are in transit from shops to building sites. The nost reliable coatings on the market are formulated to resist different kinds of abrasion that can occur before and during the installation process. These types of abrasions include marring, scratching, etching and other damage that can occur frequently at manufacturing facilities, on the road and at job sites.

4. Durability

With durability being top of mind, it’s important for architects, engineers and designers to have architectural metal panel coating options they can rely on. The architectural coating is the first layer visible on the building’s exterior and is ultimately responsible for its appearance and durability. This means the coating has the toughest job of all and must act as the first line of defense against harsh elements, including hail, acid rain, UV rays and much more. Luckily, PVDF Coatings are designed to ensure the durability of a structure and to provide exceptional resistance to harmful elements in high-stress environments.

5. Chalk and Fade Resistance

When metal is left untreated or uses coatings that aren’t made to resist the sun’s damage, UV rays can create a “chalky” film atop metal architecture. Coatings that clad metal building products have the unique challenge of protecting buildings against an array of weather conditions, specifically offering a waterproof barrier that stands up to UV rays, humidity, acid rain and corrosive salt.

Ultimately, architectural coatings provide superb protection against harsh outdoor elements and abrasion once they’ve been applied to panels. Through rigorous and continuous testing, coating manufacturers have created durable PVDF coating formulas that withstand the test of time, weather, and general wear and tear with the ultimate goal of preserving metal architecture long into the future.
