Colombia is currently undergoing a massive structural transformation. With major projects like the Bogotá Metro Line 1, the Mar 1 and Mar 2 highways, and the expansion of the Port of Buenaventura, the demand for high-strength, durable industrial flooring and stair treads has reached an all-time high. As a leading global supplier, we understand that the Colombian market requires more than just steel; it requires compliance with localized safety norms like the NSR-10 (Norma Sismo Resistente) and RETIE standards for electrical safety in industrial environments.
The industrial landscape in cities like Medellín, Cali, and Barranquilla is shifting toward high-tech manufacturing and sustainable energy. Steel stair treads serve as the literal backbone of safety in these high-traffic, high-risk environments. Whether it is a coffee processing plant in the Eje Cafetero or an offshore oil rig near the Caribbean coast, the necessity for anti-slip, corrosion-resistant galvanized steel is non-negotiable.
Ningbo Jiulong Machinery Manufacturing Co., Ltd (NJMM) was founded in 1993, is mainly engaged in the design and manufacturing of steel grating, railings, platforms and other light steel structures. It is a modern comprehensive enterprise integrating scientific research and design, machinery manufacturing and engineering construction. We currently have 2 production bases in the East and North of China, there are 12 steel grating auto welding product lines, as well as complete auxiliary processing equipment and testing facilities, like robots welding, laser cutting, digital control panel tailoring etc. Our annual output of steel gratings and allied products, including trench covers, stair treads, stanchions, handrails, fences, is over 50,000 metric tons.
NJMM offers engineering service and support, including the design and installation of the grating solutions and the provision of detailed drawings if required. NJMM is committed to a continuous process to enhance customer service through product quality and delivery. NJMM had got the ISO9001 Quality System Certificate, CE certificate, GHOST certificate and other international certificates. We believe our products are your best choice.
NJMM markets its products mainly to South America, Europe, Oceania, Africa, and the Middle East. Our "Longta" brand is synonymous with quality in large-scale infrastructure projects.
With 12 self-developed automatic pressure welding equipment lines and 6 sets of automatic banding robots, we ensure precision that exceeds international standards.
Certified by ISO9001:2015, ISO45001:2018, and ISO14001:2015. We participated in drafting the revised steel grating standard of YB/T4001 in 2019.
In the global context, industrial safety has moved towards "Active Prevention." Our stair treads incorporate advanced Information Gain technology in their design—utilizing serrated surfaces and specialized nosing that reduce slip-and-fall incidents by up to 40% in oily or wet conditions. In Colombia, where the humidity in coastal regions like Cartagena can accelerate oxidation, our Hot-Dip Galvanization process (ISO 1461 compliant) provides a protective barrier that extends the product lifecycle to over 30 years without maintenance.
The products is widely used in Petrochemical Industry, Light Chemical Industry, Mechanochemistry, Textile Chemical Industry, Refinery, Port terminal, Steel industry, Mining and refining, Shipbuilding industry, Military engineering, Airport engineering, Offshore engineering.
Recommend products: JG255/30/100, JG325/30/100. Advantages: Ventilation, lighting, heat dissipation, explosion-proof, anti-skid performance.
Recommend products: G505/30/100, JG705/30/100. Advantages: Strong loading capacity, grid structure prevents grime accumulation.
Modern style with neat appearance, easy installation with clips, and high windage resistance for high-altitude projects.
The future of industrial steel in Colombia lies in Sustainability and Digital Integration. NJMM is currently developing "Smart Grating" solutions that incorporate sensors to monitor structural integrity and load stress in real-time—a vital feature for Colombia's earthquake-prone zones. Our commitment to a "Green Factory" status aligns with Colombia’s national goal of reducing carbon emissions, as we implement more efficient galvanizing furnaces and recycled steel feedstock.
We provide full technical documentation in Spanish, customized to meet Colombian engineering requirements. Our logistics network ensures that whether you are in Bogotá, Medellín, or a remote mining site in La Guajira, delivery is handled with localized expertise and customs compliance.
Typically, ocean freight to major ports like Buenaventura or Cartagena takes 25-35 days. Production time for customized orders is usually 7-14 days depending on volume.
Yes, our design and structural calculations can be tailored to align with NSR-10 requirements for seismic resistance and load-bearing capacity.
Absolutely. We recommend our serrated steel series for cities with high precipitation like Quibdó or during the Colombian rainy season to ensure maximum grip.
We specialize in Hot-Dip Galvanization with a coating thickness that exceeds ASTM A123, specifically designed to withstand the saline air of Barranquilla and Santa Marta.
