In the field of architecture, color coated roofing sheets are widely used in roof engineering of industrial plants, commercial buildings, and residential buildings due to their beautiful appearance, durability, and strong anti-corrosion performance. However, there are significant differences in the requirements for the width of roof panels in different scenarios, and how to choose the appropriate specifications has become a focus of attention for both design and construction parties. This article will systematically analyze the width standards, influencing factors, and selection recommendations for color coated roofing sheets.

1. Specification of the roller set of the molding machine (the most critical factor)

The final width of the roof panel is determined by the manufacturer's molding machine. Different models of molding machines can produce plate shapes with varying heights and spacing of wave peaks, resulting in different widths.

2. Plate type (corrugated shape)

Different board types are the main differences that determine the width and purpose of color coated roofing sheets. The common types of roof panels and their typical effective coverage widths are as follows (please note that these are common specifications in the industry, and specific dimensions vary from manufacturer to manufacturer):

1. Ordinary Jiaochi 820 type: effective coverage width ≈ 820mm

(This is a very classic board shape, meaning that after being pressed and unfolded, one board can cover a width of 820mm)
2. Jiaochi 760 type: effective coverage width ≈ 760mm
Hidden (bite type) board type: The effective coverage width is usually between 400mm-600mm
(such as 468mm, 500mm, etc., commonly used in large public buildings, beautiful and with good weather resistance)
3. Corrugated board (YP series): effective coverage width ≈ 750mm-900mm
(For example, YX75-830 type, with a coverage width of 830mm)
4. Clear nail board type: The effective coverage width is usually between 750mm-1000mm

(Plate type with exposed screws, easy to install)

3. Important concept differentiation:

1. Unfolding width: refers to the width of the flat plate (color coated roll) before pressing, which is usually greater than 1 meter.

2. Effective coverage width: refers to the actual width of the roof that can be covered by a color coated roofing sheet after pressure installation. This is the size that you need to pay the most attention to in procurement, design, and construction. For example, an 820 type board has a coverage width of 820mm. Use this size to calculate how many boards are needed for a roof.

4.How to obtain accurate dimensions?

The most reliable method is to directly consult with the color coated roofing sheet manufacturer or supplier you plan to purchase, and provide the panel model you want. They will provide you with accurate:
1. Effective coverage width
2. Peak height
3. Theoretical weight per meter
4. Allow key technical parameters such as maximum span.
The width of color coated roofing sheets is not a standard value, but is determined by the panel type and production equipment. When making a selection, please make sure to confirm the "effective coverage width" of the selected board type with the supplier to ensure the accuracy of engineering calculations.
