Sihe Steel
Engineered to withstand high pressures, environmental oxidation, and intense mechanical fatigue.
Operating from our highly integrated facility in China, Liaocheng Sihe Stainless Steel Material LTD is a leading expert in the engineering and supply of high-grade stainless steel products. With six modern production lines and over a decade of metallurgy experience, we supply critical components to demanding sectors worldwide.
Our core capabilities span across the manufacture of stainless steel coiled tube, stainless steel polishing tube, and stainless steel seamless coiled tubing. We rigorously execute our production processes in strict compliance with GB, ASTM, ASME, JIS, and EN standards. By bridging raw material processing with precision surface finish engineering, we deliver superior raw materials, structural frames, and decorative sheets specifically designed for Elevator Stainless Steel Doors, architectural panels, and mechanical assemblies.
Our metallurgy grades include standard austenitic alloys like 304/304L, 316L, 321, 317L, 309S, 310S, duplex/super duplex grades such as 2205 and 2507, as well as ultra-corrosion-resistant nickel-chromium alloys like INCOLOY 800, INCOLOY 825, and INCONEL 625.
How high-purity alloy sheets and tubing technology integrate to construct modern high-rise elevator systems.
Elevator doors undergo thousands of cycles daily, requiring high tensile strength and fatigue resistance. Standard ASTM A240 Grade 304 and 316L stainless steel sheets supply the core structural paneling. For marine environments or high-humidity coastal zones, Duplex 2205 delivers superior pitting and corrosion resistance.
Elevator interior design demands high aesthetic standards. Liaocheng Sihe offers precision-polished plates featuring Mirror 8K, Hairline, Etching, and PVD titanium coatings (Gold, Bronze, Rose Gold, Black). Additionally, nano-ceramic anti-fingerprint coatings protect the panels from smudges, improving wear resistance.
Hydraulic elevator systems rely on seamless fluid dynamics. Our stainless steel hydraulic tubing and coiled tubing, ranging in diameter from 0.125 inch (3.175 mm) to 1 inch (25.4 mm), are engineered with wall thicknesses up to 0.165 inch (3 mm). These components offer seamless performance for high-pressure control lines.
Global elevator manufacturers require supply chain stability. At Liaocheng Sihe, we address this demand through lean manufacturing processes. Our plant runs three dedicated production lines for stainless steel coils and tubes, keeping high-frequency processes online to support fast mass-production runs.
We implement bright annealing technology online. This process heats the alloy in a controlled protective atmosphere of hydrogen and nitrogen, preventing scaling and ensuring a clean, highly flexible grain structure. The resulting products are ideal for deep drawing, stamping, and complex bending of elevator door headers, tracks, and frames.
Quality is verified before shipping. We conduct a comprehensive range of structural and material integrity tests on our products, including:
Supplying standard and custom alloy configurations to meet high mechanical and environmental demands.
Aesthetic elevator door skins featuring hairline, mirror, and scratch-resistant physical vapor deposition (PVD) coatings for high-traffic public areas.
Utilizing highly corrosion-resistant Duplex 2205, Inconel 625, and Incoloy 825 alloys to withstand salt spray and harsh marine atmospheres on offshore rigs and cruise ships.
High-purity SUS316L mirror-finish door panels designed to withstand chemical disinfectants and washdown protocols without surface pitting.
Reinforced structural profiles and door frames designed for high impact resistance and load capacity in subways, airports, and factories.
Our products are certified by international inspection organizations to meet global building code requirements.
Providing custom cutting, forming, and finishing solutions to meet precise project tolerances.
We support various materials (e.g., 304, 316L, 2205) and custom specifications, offering flexible options for stainless steel coils with outer diameters from 6.35 mm to 19 mm.
Includes precise bending, spiral forming, and precision drawing, designed specifically for heat exchangers, structural support frames, and elevator door tracks.
Laser cutting, mechanical cutting, and flame cutting options provide clean edges, high dimensional accuracy, and optimized material usage.
Dedicated to developing clean surface profiles, including mirror polished, sandblasted, anti-fingerprint, and color PVD coatings.
Engineered flanging for secure connections, widely used in automotive exhaust networks, chemical piping, and elevator door structural framing.
Our stainless steel alloys support critical functions across diverse industrial sectors.
Technical guidance for global elevator manufacturers, architectural designers, and procurement managers.
