Let us introduce the unparalleled features of our innovative plastic steel ladder, designed to redefine excellence in drainage inspection.
Material Composition: Crafted with an outer layer of high-strength, engineering-grade copolymer polypropylene plastic, renowned for its superior resistance to high temperatures, humidity, deformation, and detachment. This ladder is further reinforced with premium round or threaded steel from Jinan Iron and Steel Group, available in robust diameters of 16mm or 20mm, ensuring exceptional strength and durability.
• Performance Characteristics
Unmatched Durability: Engineered for excellence, our ladder showcases outstanding corrosion resistance, effortlessly withstanding harsh chemical exposures such as ultraviolet radiation and acid or alkali attacks. With a remarkable endurance, it thrives in extreme environments ranging from -15°C to 100°C, guaranteeing a service life of up to 50 years when embedded underground, and up to 20 years above ground, making it a long-term investment in quality.
Safety and Reliability: Marrying aesthetics with functionality, this ladder is not only visually appealing but also offers exceptional anti-slip performance, high-impact resistance, and a stable, strong load-bearing structure. Some models come equipped with safety-enhancing handrails and anti-slip locks. Non-conductive, fire-resistant, and heat-tolerant, it prioritizes user safety above all.
Effortless Installation and Maintenance: Experience the simplicity of quick and seamless installation, with the ability to embed directly into walls pre-installation. Its smooth surface minimizes dust accumulation and allows for easy, regular cleaning with just water. Boasting a formidable anti-aging capability, it significantly reduces the inconvenience of frequent replacements.
Wide Application Range: Versatile and adaptable, this ladder is ideal for various settings, including inspection wells, water towers, civil defense projects, slope subway tunnels, and both industrial and residential buildings. It serves as a reliable, fixed stair solution, particularly thriving in environments like sewage inspection wells, cable wells, and sand wells.
