Engineered for high-load environments and maximum slip resistance.
Redefining Industrial Safety and Architectural Durability in a Global Market.
In the contemporary industrial landscape, High-Quality Stair Treads Steel represent more than just a functional necessity; they are a critical component of safety engineering and asset longevity. As global infrastructure faces increasing environmental challenges and stricter safety regulations (such as OSHA in the US and EN standards in Europe), the role of specialized manufacturers like Ningbo Jiulong Machinery Manufacturing Co., Ltd (NJMM) has become paramount.
Founded in 1993, NJMM has pioneered the integration of scientific research, digital manufacturing, and engineering support. With an annual output exceeding 50,000 metric tons, we address the complex procurement needs of the world's most demanding sectors: petrochemical, mining, offshore engineering, and large-scale logistics hubs.
Modern industrial trends focus on serrated surfaces and high-friction nosing designs to eliminate workplace slips in oily or icy conditions. Our JT series offers customized nosing for peak safety.
The global shift toward sustainable procurement means sourcing stair treads with high recycled content and energy-efficient galvanization processes (Hot Dip Galvanizing) to minimize life-cycle carbon footprints.
Pre-engineered stair treads allow for "Plug & Play" installation on site. This reduces labor costs by up to 40% and ensures perfect alignment in complex steel structures.

How NJMM integrates digital intelligence into heavy steel manufacturing.
At NJMM, "China Factory 4.0" is not a buzzword—it is our operational reality. By utilizing 12 self-developed automatic pressure welding equipment lines and 6 sets of automatic banding robots, we ensure that every steel stair tread meets a tolerance level of within 0.5mm. This digital precision translates to seamless installation at the client's site.
Meeting the needs of International EPC Contractors and Industrial End-Users.
In refineries and sea platforms, salt spray and chemicals demand high-spec Hot Dip Galvanized (HDG) steel. Our JG325/30/100 series provides 50+ years of anti-corrosion life.
Heavy duty stair treads must withstand vibrations and impact. We utilize forge-welding technology to ensure bar-to-bar fusion that exceeds traditional manual welding strengths.
For parking lots, airports, and water treatment plants, we provide lightweight aluminum and galvanized steel solutions that balance aesthetic modern style with superior drainage.
Proven excellence through international certification and standard drafting.
NJMM participated in drafting and revising the steel grating standard of YB/T4001 in 2019. We don't just follow standards; we help define them. As a "High-Tech Enterprise" and "Green Factory," we ensure our steel treads meet the YB/T4001, ANSI/NAAMM (MBG531), and British BS4592 standards.
Answering common engineering and procurement questions.
JT1 is for welding installation without nosing; JT2 is for bolt fixing with a checkered plate nosing for added safety; JT4 is for welding installation with checkered plate nosing. The choice depends on your site's assembly requirements.
Load capacity depends on the span and the bearing bar size (e.g., 32x5mm). Our JG325 series can typically handle heavy foot traffic and light equipment loads across spans up to 1200mm.
Hot-dip galvanized steel offers the best cost-to-performance ratio for industrial environments. It provides sacrificial protection against rust, whereas aluminum is lighter and stainless steel is reserved for extreme hygiene (food/pharma).
Standard widths are 125, 155, 185, 215, 245, 275, and 305mm. Lengths are typically customized between 600mm to 1200mm depending on the staircase structure.
Yes, our products carry CE certification and meet European, American, and Australian standards. We provide MTC (Mill Test Certificates) with every shipment.
Absolutely. Our engineering team provides comprehensive support, including CAD drawings and 3D models to ensure the grating solutions fit perfectly into your larger structural projects.
