When sourcing hollow component rectangles for construction or industrial projects, one of the first questions procurement managers ask is: what is the price per unit, and how does bulk ordering affect the cost? The answer depends on several variables, including material type, dimensions, wall thickness, and order volume. This article breaks down the key pricing factors and explains how working with an experienced hollow component rectangle supplier can help you secure competitive pricing for large-scale orders.
Hollow component rectangles — also known as rectangular hollow sections (RHS) — are structural steel or metal profiles with a rectangular cross-section and a hollow interior. They are widely used in construction, infrastructure, and industrial fabrication due to their excellent strength-to-weight ratio, aesthetic appeal, and ease of welding and connection.
Common applications include building frames, columns, beams, bridges, machinery, scaffolding, and architectural features. They are available in various materials including carbon steel, stainless steel, aluminum, and galvanized steel, each offering different performance characteristics and price points.
The base material is the single largest cost driver. Carbon steel (such as Q235 or S235JR) is the most economical option, typically ranging from $500 to $750 per ton depending on market conditions. Stainless steel hollow sections cost significantly more — often 3 to 5 times the price of carbon steel — due to the alloying elements like chromium and nickel. Aluminum rectangular hollow sections fall somewhere in between, offering corrosion resistance at a moderate premium.
Larger cross-sections and thicker walls require more raw material, directly increasing the per-unit cost. A 100mm x 50mm x 3mm rectangular hollow section will cost substantially less than a 200mm x 100mm x 10mm section. The table below illustrates typical size-to-price relationships:
| Size (mm) | Wall Thickness (mm) | Approx. Weight (kg/m) | Relative Cost Factor |
|---|---|---|---|
| 50 x 25 | 2.5 | 2.72 | 1.0x (baseline) |
| 80 x 40 | 3.0 | 5.19 | 1.9x |
| 100 x 50 | 4.0 | 8.59 | 3.2x |
| 150 x 100 | 6.0 | 21.10 | 7.8x |
| 200 x 100 | 8.0 | 34.00 | 12.5x |
Raw (black) hollow sections are the most affordable. Galvanized (zinc-coated) sections add roughly 15–25% to the base cost but provide essential corrosion protection for outdoor or humid environments. Powder coating and painting add further costs depending on the specification.
Products manufactured to international standards such as EN 10219, EN 10210, ASTM A500, or JIS G3466 may carry a price premium due to stricter quality control and testing requirements. However, certified products reduce project risk and are often mandatory for regulated construction projects.
Bulk ordering is the most effective way to reduce the per-unit cost of hollow component rectangles. Here is how volume affects pricing:
Small orders (under 5 tons): Buyers typically pay the highest per-unit rate. Mills and distributors charge a premium for small batches due to handling and logistics overhead.
Medium orders (5–25 tons): A noticeable price reduction of 5–12% is common. Suppliers can optimize production runs and shipping consolidation.
Large orders (25+ tons or container loads): The most competitive pricing tier. Discounts of 15–25% or more are achievable, especially when ordering directly from the manufacturer or through a well-connected building material supplier with established factory relationships.
Additionally, long-term supply contracts with scheduled deliveries can lock in favorable pricing and protect against market fluctuations in raw material costs.
Not all suppliers are equipped to handle large-volume hollow component rectangle orders. When evaluating a pipes fittings supplier or structural steel provider, look for these qualities:
