Carbon steel – Stair treads

Carbon Steel Stair Treads

1. Product Information

Carbon Steel Stair Treads (Safety Step Bar Grating) are the most cost-effective and high-strength flooring solutions for industrial staircases. As a critical component of platforms and stairways, their core function is to provide a safe, slip-resistant, and durable walking surface. We utilize premium structural carbon steel and professional manual welding to ensure every tread maintains structural integrity under frequent heavy loads.

3. Product Advantages

1.Safety & Reliability: The combination of serrated bars and Twisted Square Cross Bars, paired with specialized nosing, ensures maximum slip resistance.

2.Exceptional Quality: We strictly control the manual welding process and use premium materials to withstand the test of time and heavy traffic.

3.Efficient Installation: Accurate hole positioning and standardized designs simplify the assembly process, reducing onsite labor costs.

4.Low Maintenance: The open-grid design provides excellent Debris Shedding, allowing rain, snow, and dirt to pass through easily.

4. Core Applications

Widely used in power plants, chemical refineries, warehouses, and industrial workshops. Featuring a serrated Bearing Bar and unique anti-slip nosing, these treads provide a safe experience for high-traffic environments and are typically used in conjunction with steel grating platforms.

5. Customization Services

We offer comprehensive customization. Based on your specific dimensions, material preferences, and unique design concepts (such as special hole patterns, checkered plate nosing, or spiral staircase treads), our team crafts bespoke solutions that perfectly fit your project requirements.

6. Quality Control

1.Weld Penetration Audit: We focus on the weld quality between end plates and the grating body to prevent fatigue cracking under dynamic loads.

2.Dimensional Accuracy: Bolted treads (ST2/4/6) are checked against a 1:1 template to ensure a 100% match with your stringer hole centers.

3.Galvanizing Inspection: We monitor the zinc coating thickness to meet international standards, ensuring long-term rust protection.

7. FAQ

Q: How do I choose between Welded (ST1/3/5) and Bolted (ST2/4/6) fixing?

A: Welded treads are more permanent, while Bolted treads allow for easy individual replacement.

Q: What is the primary purpose of the Nosing (front edge)?

A: Nosing provides visual edge warning and reinforces the area under the highest impact load.

Q: Why follow the modulus width (e.g., 125mm, 155mm)?

A: It aligns with the bearing bar pitch, preventing material waste and ensuring a symmetrical grid pattern.

Q: What configuration is best for oily environments?

A: We strongly recommend Serrated Bearing Bars combined with twisted cross bars for maximum traction.

Q: Is there a maximum span limit for stair treads?

A: Generally, spans are under 1200mm. For wider stairs, we increase bearing bar depth or thickness.

Q: Are the bolt hole positions on the end plates standardized?

A: We primarily fabricate according to your drawings to ensure a perfect match with your existing stringers.

In summary, Carbon Steel Stair Treads deliver exceptional safety, reliability, and low-maintenance performance in high-traffic industrial settings such as power plants, refineries, warehouses, and workshops. With customizable designs, precise manual welding, anti-slip serrated surfaces, and efficient installation, they ensure long-term structural integrity, debris shedding, and compliance with demanding safety standards.
