Short answer: Buy from stock when you need steel within days, in small or mixed quantities, or in common sizes. Place a mill order when you need large tonnages of one product, special grades or lengths, and can wait for the next rolling cycle. Many projects combine both.
There are two basic ways to buy steel: from a stockist or service centre that already holds material, or by ordering directly from a producing mill. Each suits different needs.
How stockists work
Stockists buy in bulk from mills, hold inventory in many sizes, and sell in smaller quantities with fast delivery. Many also process steel — cutting, drilling, slitting, profiling.
Strengths: speed, flexibility, mixed orders, processing, small quantities. Limitations: higher price per tonne, limited range of special grades and lengths.
How mill orders work
Mills produce to order or in rolling campaigns, usually with minimum quantities per size and grade.
Strengths: lower price per tonne for volume, special grades and lengths, certificates direct from the producer. Limitations: minimum quantities, lead times tied to rolling schedules, less flexibility for changes.
Side by side
| Factor | Stockist | Mill order |
|---|---|---|
| Lead time | Days | Weeks to months |
| Minimum quantity | Single pieces | Tonnes per size |
| Price per tonne | Higher | Lower |
| Special grades/lengths | Limited | Available |
| Processing | Often available | Limited |
| Changes after order | Easier | Difficult |
Combining both
A typical project approach:
- Mill order the bulk tonnage of main members (for example columns and beams of a large warehouse) as early as drawings allow.
- Stock for urgent items, small quantities, secondary steel and late design changes.
This balances cost with programme risk.
Questions to ask suppliers
- Is this line physically in stock today, and how much?
- If not, which mill and which rolling date?
- Are certificates from the original mill?
- Can stock be reserved while drawings are finalised?
Clarity on stock status is one of the most important parts of comparing quotations.
When you request a quote, each line will state whether it is stock or mill supply and the expected lead time.
