Heavy - Duty Q235 Steel Drainage Grating for Efficient Water Drainage Systems

5 0 Reviews
Hot dip galvanized steel grating has a wide range of applications, commonly found in floors, stair treads, and fences. It is made of Q235 low carbon steel or stainless steel. Steel grating is a steel product made of cross-welded flat steel and horizontal bars. It is commonly used in the manufacture of manhole covers, steel structure platforms, and steel stair treads. It provides ventilation, lighting, heat dissipation, anti-slip properties, and explosion-proof properties, making it suitable for a variety of industrial environments.
Steel grating is typically made of carbon steel with a hot-dip galvanizing treatment to prevent oxidation, but can also be made of stainless steel. Its horizontal bars are typically twisted square steel or other shaped steel. The advantages of steel grating include material savings, reduced construction and maintenance costs, and easy installation and durability. Steel grating is widely used in industrial applications due to its excellent performance. Its production standards vary across different countries and regions, with China, the United States, and the United Kingdom having their own standards. Common treatments include hot-dip galvanizing, cold-dip galvanizing, painting, and anti-rust oil treatment.

Product Introduction

Hot - dipped galvanized steel grating is a highly versatile steel product extensively employed across numerous industries. It is fabricated from premium - quality steel bars using specialized manufacturing processes. The surface of the grating undergoes hot - dip galvanization treatment, endowing it with outstanding corrosion resistance. This grating offers several key advantages, including high strength, excellent load - bearing capacity, and straightforward installation. It is commonly utilized in platforms, walkways, and drainage channels.

Advantages

Core Benefits of Hot - Dipped Galvanized Steel Grating

  1. Superior Corrosion Resistance
    During the hot - dip galvanization process, a thick zinc layer is formed on the surface of the grating. This layer acts as a barrier, effectively preventing rust and corrosion. In outdoor environments, it can last for more than 20 years, making it an ideal choice for chemical plants and coastal areas.

  2. High Strength and Load - Bearing Capacity
    Crafted from high - quality steel bars with an optimized bar combination, a standard type of hot - dipped galvanized steel grating can support loads ranging from 3 to 5 tons per square meter. It is well - suited for heavy - duty industrial and high - traffic areas.

  3. Excellent Anti - Slip Performance
    The unique surface patterns of the grating increase friction. With an anti - slip coefficient greater than 0.6, it helps prevent slips on wet or dusty walkways and stair treads, enhancing safety.

  4. Easy Installation and Low Maintenance
    The grating is pre - fabricated, enabling quick installation using bolts or welding, which saves time and labor. It requires minimal maintenance, with only occasional inspections needed to reduce long - term costs.

  5. Premium Quality and High Customizability
    Our factory adheres to strict quality control measures. Each batch of steel grating undergoes rigorous inspection to ensure top - notch quality. Additionally, we can customize the size, shape, and load - bearing capacity according to customer requirements, providing solutions for projects of all scales.

Technical Parameters

  1. Material Selection
    We use Q235 low - carbon steel or stainless steel. Q235 offers good overall mechanical properties and is relatively cost - effective. Stainless steel materials such as 304 and 316 have excellent corrosion resistance and are suitable for special environments.

  2. Specification (Load - bearing Flat Bar × Cross Bar)
    Common specifications of load - bearing flat bars include 20×5, 25×5, 30×3, 30×5, 40×5, 50×5, etc. (unit: mm). Common specifications of cross bars are 5×5, 6×6, 8×8, etc. (unit: mm). Different combinations of these specifications can meet various load - bearing requirements.

  3. Mesh Size
    Commonly used mesh sizes are 30×100, 40×100, 60×100 (unit: mm), etc. Smaller mesh sizes are ideal for occasions with high safety protection requirements to prevent small objects from falling. Larger mesh sizes focus more on functions such as ventilation and drainage and have relatively lower costs.

  4. Thickness of Galvanized Layer
    After hot - dip galvanization, the average thickness of the galvanized layer is not less than 85μm, and the local thickness is not less than 70μm. This thickness meets national standards, effectively ensuring the product's corrosion resistance and extending its service life.

  5. Bearing Capacity
    The bearing capacity varies depending on the specifications. For example, for a steel grating with the specification of 303/30/100, the uniform load can reach 3.5kN/m², and the concentrated load can reach 3.85kN. The appropriate specification can be selected based on the load requirements of the actual use scenario.

  6. Surface Treatment
    The hot - dip galvanization process is the primary surface treatment method, forming a uniform and dense zinc layer on the surface of the steel grating, greatly enhancing its corrosion resistance. In addition, other surface treatments such as cold galvanization and painting can also be carried out according to customer needs.

Installation and Usage Guidelines

Before installation, carefully check the size and quality of the hot - dipped galvanized steel grating. During installation, accurately align the grating and secure it firmly using bolts or welding. When using the grating in high - load areas, ensure that the load does not exceed its capacity. Regularly inspect the grating for any signs of damage or corrosion. Following these simple steps ensures the long - term and safe use of the steel grating.

Frequently Asked Questions (FAQ)

  1. Q: What is the service life of the hot - dipped galvanized steel grating?
    A: Under normal outdoor conditions, it can last for more than 20 years due to the thick anti - corrosion zinc layer. However, the lifespan may vary in special environments such as chemical plants.

  2. Q: Can the steel grating be customized?
    A: Absolutely. We can customize the size, shape, and load - bearing capacity according to your specific needs. Just inform us of your requirements.

  3. Q: What is the installation process like?
    A: The installation process is quite simple. First, accurately align the grating. Then, secure it using bolts or welding. The short installation time saves you both time and labor costs.

  4. Q: How should the hot - dipped galvanized steel grating be maintained?
    A: Maintenance is easy. Conduct occasional inspections. Since it has high corrosion resistance, there is no need for frequent upkeep. Only repair it if any damage is found.
