一、彩鋼板的核心構造：三層結構的 “防護鎧甲”

1、 The core structure of color steel plate: a three-layer structure of "protective armor"

彩鋼板的構造可以簡單理解為 “三明治” 結構，由三層不同材料組成：

The construction of color steel plates can be simply understood as a "sandwich" structure, consisting of three layers of different materials:

基層鋼材：多為鍍鋅鋼板或鍍鋁鋅鋼板，厚度在 0.3-1.2 毫米之間。鍍鋅鋼板表面覆蓋著一層均勻的鋅層（鋅層厚度 8-275 克 / ），就像給鋼材穿上 “防銹內衣”，能有效抵抗空氣中的水汽和輕微腐蝕；鍍鋁鋅鋼板則在鋅層中加入鋁元素，耐腐蝕性是普通鍍鋅板的 2-3 倍，適合潮濕或有輕微酸雨的環境。

Base steel: mostly galvanized steel sheet or aluminum zinc coated steel sheet, with a thickness between 0.3-1.2 millimeters. The surface of galvanized steel sheet is covered with a uniform layer of zinc (with a thickness of 8-275 grams per square meter), which is like putting a "rust proof underwear" on the steel, effectively resisting moisture and slight corrosion in the air; Aluminum zinc coated steel plate adds aluminum element to the zinc layer, and its corrosion resistance is 2-3 times that of ordinary galvanized steel plate, suitable for humid or slightly acid rain environments.

涂層材料：基層鋼材表面會涂上一層或多層涂料，常見的有聚酯（PE）、硅改性聚酯（SMP）、氟碳（PVDF）等。聚酯涂層顏色豐富（如天藍、銀灰、磚紅），性價比高，適合普通環境；氟碳涂層則像 “防護外套”，抗紫外線和耐候性強，10 年以上不褪色，適合戶外長期使用或對美觀要求高的建筑。

Coating material: The surface of the base steel will be coated with one or more layers of paint, commonly including polyester (PE), silicon modified polyester (SMP), fluorocarbon (PVDF), etc. Polyester coating comes in a variety of colors (such as sky blue, silver gray, brick red), with high cost-effectiveness, suitable for ordinary environments; Fluorocarbon coating is like a "high-end protective jacket", with strong UV resistance and weather resistance. It will not fade for more than 10 years and is suitable for long-term outdoor use or buildings with high aesthetic requirements.

基板處理：鋼材在涂漆前會進行脫脂、磷化等預處理，就像 “洗臉護膚”，確保涂層與鋼材緊密結合，不易脫落。

Substrate treatment: Steel is pre treated with degreasing, phosphating, etc. before painting, just like "face washing and skincare", to ensure that the coating is tightly adhered to the steel and not easily peeled off.

這種三層結構讓彩鋼板既有鋼材的強度，又有涂層的裝飾性和保護性，成為建筑材料中的 “多面手”。

This three-layer structure allows color steel plates to possess both the strength of steel and the decorative and protective properties of coatings, making them a versatile choice in building materials.

二、彩鋼板的顯著優勢

2、 The significant advantages of colored steel plates

1. 耐腐蝕，壽命長

1. Corrosion resistance and long service life

在禹城的氣候條件下，彩鋼板的鍍鋅或鍍鋁鋅基層能有效抵抗夏季的潮濕和冬季的干燥，涂層則阻擋紫外線對鋼材的直接照射。例如，普通聚酯涂層彩鋼板在室內或干燥環境中可使用 10-15 年，氟碳涂層彩鋼板在戶外可使用 20 年以上，比普通鋼板的壽命延長 3-5 倍。

Under the climatic conditions of Yucheng, the galvanized or aluminum zinc coated base layer of color steel plates can effectively resist the humidity in summer and the dryness in winter, while the coating blocks direct exposure of ultraviolet rays to the steel. For example, ordinary polyester coated color steel plates can be used for 10-15 years indoors or in dry environments, while fluorocarbon coated color steel plates can be used for more than 20 years outdoors, extending their lifespan by 3-5 times compared to ordinary steel plates.

2. 輕便快捷，安裝省力

2. Lightweight and fast, easy to install

彩鋼板的密度僅為鋼材的 1/3，每重量 10-15 公斤，搬運和安裝比傳統磚瓦建筑節省 50% 的人力。施工時只需用螺絲或卡扣將彩鋼板固定在鋼結構或木質框架上，無需水泥澆筑和漫長養護，一個 500 的廠房屋頂，3-5 天就能完成安裝，大大縮短工期。

The density of color steel plate is only one-third of that of steel, with a weight of 10-15 kilograms per square meter. It saves 50% of labor in handling and installation compared to traditional brick and tile buildings. During construction, only screws or buckles are needed to fix the color steel plate to the steel structure or wooden frame, without the need for cement pouring and long maintenance. A 500 square meter factory roof can be installed in 3-5 days, greatly shortening the construction period.

4. 性價比高，應用廣泛

4. High cost-effectiveness and wide application

彩鋼板的比傳統建筑材料（如石材、鋁板）低 30%-50%，卻能實現相似的裝飾和防護效果。例如，搭建一個 1000 的倉儲大棚，使用彩鋼板的成本約為 8-12 萬元，而使用其他材料可能需要 15-20 萬元，性價比優勢明顯。

The price of color steel plate is 30% -50% lower than traditional building materials such as stone and aluminum plate, but it can achieve similar decorative and protective effects. For example, building a 1000 square meter storage greenhouse using color steel plates costs about 80000 to 120000 yuan, while using other materials may cost 150000 to 200000 yuan, with obvious cost-effectiveness advantages.
