Product Overview
Economical roofing solution that doesn't compromise on quality. Hot-dip zinc coating delivers reliable corrosion protection, while corrugated profile provides structural strength needed for long-term performance.
Product Description
Shandong Jinlisheng’s Corrugated Galvanized Roofing Steel Sheets are engineered for residential, rural house, and warehouse roofs, with exceptional corrosion resistance as a standout feature. Made via high-quality hot-dip galvanizing, they have a 30-120g/m² zinc coating that forms a tight, impermeable protective layer—effectively blocking rain, snow, humidity, and even mild industrial fumes from damaging the base steel, preventing rust and corrosion for years.
The corrugated design also boosts structural stability, suiting warehouse snow loads and rural harsh weather. Lightweight (10-14kg/㎡) for easy installation, it maintains long-lasting performance (15+ years outdoors) with little maintenance. Compliant with GB/T 2518 and ASTM A653, it’s a reliable, corrosion-proof choice for diverse roofing needs.

Key Features & Highlights
Superior Corrosion Resistance: The hot-dip galvanized zinc coating acts as a sacrificial layer, providing long-term protection against rust and corrosion, even in harsh and humid environments.
High Structural Strength: The corrugated profile gives the sheets exceptional load-bearing capacity and resistance to wind uplift, making them suitable for regions with heavy snow or strong winds.
Long Service Life & Durability: The combination of strong steel and a robust zinc coating ensures a long service life with minimal maintenance, offering excellent value over time.
Cost-Effective Solution: As one of the most economical roofing and cladding options available, it provides reliable protection for a wide range of structures without a high initial investment.
Versatility & Wide Application: Its simple, functional design makes it suitable for a vast array of structures, from warehouses and factories to farm sheds and fences.

FAQ
Q1: How long does galvanized roofing last?
A: Galvanized roofing typically lasts 15-25 years depending on environment. Rural environments: 20-25 years. Industrial/coastal: 10-15 years. Regular maintenance extends service life.
Q2: Does galvanized roofing need painting?
A: Not required for corrosion protection. Some owners paint for aesthetic reasons after 10-15 years when zinc weathers. Pre-painted options available if color desired from installation.
Q3: What zinc coating weight is recommended for roofing?
A: Z120-Z180 (120-180 g/m²) is standard for roofing applications. Heavier coatings (Z200-Z275) provide extended life in harsh environments. Lighter coatings acceptable for temporary or protected applications.
Q4: Can galvanized roofing be walked on?
A: Yes, but with care. Walk on flat areas between corrugations, not on ridges. Use soft-soled shoes. Avoid walking when wet or frosty. Place walk boards for frequent access areas.
Q5: Is galvanized roofing noisy in rain?
A: Metal roofing is noisier than shingles or tiles in heavy rain. Insulation in ceiling reduces noise significantly. Some people find rain on metal roof pleasant; others prefer additional sound insulation.
DX51D Galvanized steel is a type of steel that has been treated with zinc to enhance its corrosion resistance.
