Painted Head Roofing Sheet Screws

Color-Matched Roofing Screws Manufactured to Your International Color Code

SANN MUO Painted Head Roofing Sheet Screws are designed for metal roofing, roofing sheet fastening, steel-to-steel assembly, and steel-to-timber applications where both reliable fastening and a clean finished appearance are important.

Unlike standard roofing screws with a fixed-color head, SANN MUO can manufacture the painted screw head according to the international color code or color reference provided by the customer.

Customers can provide RAL, Pantone, or other internationally recognized color references, allowing the screw head color to be developed to coordinate with the customer's roofing sheets, wall panels, building materials, or branded products.

Combined with multiple drilling-point options, material choices, sizes, and customized configurations, SANN MUO provides a flexible solution for roofing manufacturers, distributors, construction-material suppliers, and OEM customers.

Color-Matched Roofing Screws for Metal Roofing

For modern metal roofing systems, roofing screws are often visible after installation.

A standard unpainted screw can create a noticeable contrast against a colored roofing sheet. A color-matched screw head provides a more integrated appearance by coordinating the fastener with the roofing panel.

SANN MUO Painted Head Roofing Screws are designed to provide both functional fastening and visual coordination.

Customized Roofing Screws Based on International Color Codes

SANN MUO can manufacture painted screw heads according to international color codes provided by customers.

Customers can provide their required color reference, such as RAL, Pantone, or another internationally recognized color standard.

The specified color reference can then be used as the basis for developing the painted screw head color.

Supported Color References

Customers can provide:

• RAL color codes
• Pantone color codes
• Other internationally recognized color references
• Customer-specified color samples

This allows roofing screw colors to be developed according to the customer's existing product specifications rather than relying on a limited selection of standard screw colors.

Match Your Roofing Screws to Your Product Color

Color matching is particularly valuable when the screw head remains visible after installation.

By coordinating the screw head with the roofing sheet or building panel, manufacturers can create a more consistent appearance across the complete roofing system.

Color Matching Benefits

Reduce Visual Contrast
The screw head can be matched more closely to the roofing sheet, reducing the visual difference between the fastener and the panel.

Improve Finished Appearance
Color-matched fasteners help create a cleaner and more consistent roof appearance.

Match Different Roofing Colors
Manufacturers can specify different screw colors for different roofing sheet colors.

Support OEM Product Requirements
OEM customers can specify their own color references as part of their product requirements.

Maintain Product Consistency
Using an established international color code provides a consistent reference for future production orders.

The appropriate drilling point can be evaluated according to the customer's actual material thickness and fastening application.

Material Options for Painted Roofing Screws

SANN MUO provides several material options to accommodate different roofing and construction environments.

Stainless Steel 304

Suitable for applications requiring stainless steel construction and improved corrosion resistance.

Stainless Steel 316

Suitable for applications requiring higher corrosion resistance in more demanding environments.

Stainless Steel 410

Available for applications requiring a martensitic stainless steel material.

Carbon Steel 1018 / 1022

Suitable for general roofing and sheet metal fastening applications.

Alloy Steel 10B21 / 10B33

Available for applications requiring alloy steel material.

The appropriate material should be selected according to environmental exposure, required mechanical performance, surface treatment, and application conditions.

How to Select the Right Painted Roofing Screw

The correct roofing screw configuration depends on several factors.

1. Identify the Substrate

Determine whether the screw will be installed into steel, timber, or another substrate.

2. Check Material Thickness

The total thickness of the roofing sheet and supporting material should be considered when selecting screw length and drilling point.

3. Select the Drilling Point

Choose from #1 to #5 according to the material thickness and required drilling capacity.

4. Select the Screw Material

Choose the appropriate stainless steel, carbon steel, or alloy steel according to the application and environmental conditions.

5. Provide the Color Reference

For visible roofing applications, provide the required RAL, Pantone, or other international color code for screw-head color matching.

6. Confirm the Screw Dimensions

Select the appropriate diameter and length according to the roofing system and required fastening depth.
