FAQ
1: What is a hollow steel pipe, and what shapes are available?
▼
A hollow steel pipe (also called a hollow section or hollow structural section, HSS) is a steel tube with a hollow interior cross-section, available in square, rectangular, and round profiles. Square and rectangular hollow sections (SHS/RHS) are especially popular in structural and construction applications due to their uniform load distribution and clean aesthetic. Round hollow sections are widely used in mechanical engineering, conveyor systems, and marine & offshore frameworks. We supply hollow sections in a full range of standard and custom dimensions to meet B2B project specifications.
2: What is the difference between square hollow section and rectangular hollow section steel pipe?
▼
A square hollow section (SHS) has equal width and height on all four sides, making it ideal for columns, frames, and supports where uniform strength in all directions is needed. A rectangular hollow section (RHS) has differing width and height dimensions, providing greater bending resistance along one axis — commonly used in beams, lintels, and horizontal structural members. Both are available in a wide range of wall thicknesses and lengths, with bulk custom cutting and processing services available for large project orders.
3: Can hollow steel pipes be hot-dip galvanized, and what corrosion protection options do you offer?
▼
Yes. All of our hollow steel pipes and hollow sections can be processed with hot-dip galvanizing, which provides long-lasting zinc-based corrosion protection — particularly important for outdoor structures, construction scaffolding, and marine environments. We also offer heat treatment (hardening & tempering), polishing, and painting/coating as value-added surface treatment options, ensuring the finished product meets your project's environmental and durability requirements.
4: What are your MOQ, lead time, and available delivery terms for hollow steel pipe orders?
▼
We support both small trial orders and large-volume procurement. Our standard lead time is 15–30 days depending on specification and quantity, with express production available for urgent project needs. We offer flexible shipping arrangements including FOB, CIF, and CFR, and work directly with freight forwarders experienced in serving construction and infrastructure projects across the Middle East, East Asia, and Eastern Europe. All orders are backed by full pre-shipment inspection documentation.
5: What processing services do we provide before shipment for buyers?
▼
We offer comprehensive in-house value-added processing to ensure hollow sections arrive project-ready: Cutting & sawing — to exact length per order Bending & punching — for structural and fabrication applications Welding & assembly — partial fabrication available for OEM clients Hot-dip galvanizing — for corrosion protection in outdoor and marine environments Heat treatment (hardening & tempering) — for enhanced mechanical performance This eliminates the need for downstream processing on your end, reducing total procurement cost and project lead time.
