Pipe For Stair Railing Handrails Stainless Steel For Construction Use

Zhejiang Shuangsen Metal Technology Co., Ltd. supplies Pipe For Stair Railing Handrails Stainless Steel For Construction Use, utilizing advanced manufacturing technologies to meet the demands of modern architecture. The production line includes 133 complete sets of industrial welded pipe assembly equipment, featuring foreign-level online roundness control, internal weld leveling, and bright solid melting heat treatment. These pipes are produced from refined domestic steel, processed through 26 forming stages to ensure straightness, surface finish, and structural consistency. Material selection includes grades 201, 304, 316L, and other options, each chosen for specific environmental conditions. The product range includes round, square, and rectangular profiles with wall thicknesses from 0.5mm to 4.0mm, accommodating various design and load requirements. Surface finishes are available in bright annealed (400# to 600#), sanded (180# to 320#), and plain cold-rolled conditions, allowing for integration into different architectural styles. Complete testing protocols ensure dimensional precision, weld integrity, and surface quality, supporting reliable installation and long-term performance in construction applications.

Material Grades & Environmental Suitability

Material selection is critical for handrail systems exposed to varying environmental conditions. The following table lists available grades with their corresponding designations and recommended applications based on pollution and exposure levels.

Dimensional Specifications & Available Profiles

This Pipe For Stair Railing Handrails Stainless Steel For Construction Use is available in a variety of shapes and sizes to accommodate different handrail designs. The following tables outline the dimensional ranges for round, square, and rectangular profiles. Wall thickness options range from 0.5mm to 4.0mm, with diameters or side lengths varying according to profile type.

Fabrication & Quality Control

The Pipe For Stair Railing Handrails Stainless Steel For Construction Use manufacturing process for this equipment uses domestic large steel mill refined material and imported high-end pipe welding machines. The 26-step forming process ensures consistent weld quality, effectively avoiding defects such as porosity or incomplete fusion. Strict control over the "five degrees" – angle, flatness, brightness, bending resistance, and tensile strength – guarantees that each piece meets the required structural and aesthetic standards. Testing methods include flattening tests, bending tests, expanding tests, and optional mechanical property tests, salt spray tests, water pressure tests, and eddy current tests. Surface roughness detection is performed to ensure consistent finish quality.
