1. What exactly does "small specification" refer to in cold-rolled coils, and what key parameters need to be clarified during procurement?
A: In steel trading, "small specification" generally refers to cold-rolled coils that are not the mainstream standard size in the market. Essentially, these are products with thinner thicknesses (e.g., less than 0.5mm) or narrower widths (e.g., less than 1000mm), commonly used in precision manufacturing, small household appliances, and hardware components.
Unlike standard specifications, procurement of small specifications requires precise control over various parameters:
Thickness: Varies from ultra-thin (0.1mm) to standard thin plates (1.0mm).
Width: Narrow as 10mm, wide as approximately 1000mm.
Grade/Material: Such as SPCC, DC01, ST12, etc.
Surface Quality and Mechanical Properties: Specific indicators must be clarified based on the application (stamping, bending, etc.).
2. When looking for suppliers of small-specification cold-rolled coils, which channels should be the focus?
A: The key to sourcing small-specification cold-rolled coils is finding suppliers who are "slitting mills," "trading companies," or provide "retail" services. Large steel mills typically do not accept small orders, so the intermediary is crucial.
You can start with the following channels:
Spot trading platforms: B2B platforms such as Alibaba and Made-in-China.com often have suppliers offering cold-rolled coils with minimum order quantities as low as 1 ton or even 100 kg.
Professional steel traders: They purchase large coils from steel mills and then slitting, leveling, and processing them to meet small-specification needs. For example, some traders can provide small coils with a thickness of 0.3-1.5mm and a width of 1000-1250mm.
Local metal material companies: These companies typically serve the local market, are highly flexible, and can provide small batches of various specifications of spot goods. Some can even provide delivery services to factories.
3. What is the Minimum Order Quantity (MOQ) for small-scale purchases? How can the purchasing threshold be lowered?
A: The MOQ for cold-rolled coils varies greatly. In regular trade, the MOQ is usually 25 tons (one 20-foot container) or higher. However, for small-scale purchases, the MOQ can be significantly reduced through the right channels.
Several low MOQ options are available in the market:
As low as 1 ton: Many traders or retail platforms, such as Shanghai Caojin Industry mentioned above, have a MOQ of 1 ton.
Negotiable "trial order" quantity: Some platforms display a MOQ of "≥1 piece or ton," meaning it is negotiable.
Up to 100 kg: Some companies providing custom cutting services can reduce the MOQ to the 100 kg level.
4. What are the price differences between small-diameter cold-rolled coils and regular-diameter ones?
A: The price per ton of small-diameter cold-rolled coils is usually significantly higher than that of regular-diameter coils. The price difference mainly stems from differences in production costs and procurement models.
Thinner coils, higher prices: According to market data from April 2026, the average price of 0.5mm cold-rolled coils was 3985 yuan/ton, while the mainstream average price of 1.0mm was 3798 yuan/ton, a price difference of approximately 187 yuan/ton for thinner products.
Small order procurement costs increase: Purchasing small batches through platform retail or trading companies may include additional processing and logistics costs. For example, some retail platform quotations may be much higher than the market average price, requiring careful calculation.
Significant brand price differences: For the same specification, there are price differences between different brands. Taking the 1.0mm specification in the Chengdu market as an example, the Panzhihua Iron and Steel brand is quoted at 3810 yuan/ton, while external brands such as Liuzhou Iron and Steel and Jinhua Iron and Steel can be quoted 70-80 yuan/ton lower. When choosing, it is necessary to weigh brand and cost.
5. What are the special considerations for logistics and receiving/inspection of small-specification purchases?
A: The risks in transporting and inspecting small-specification cold-rolled coils lie in their small size, heavy weight, and fragile surface.
Logistics: Emphasis is placed on professional protection.
Securation and Shock Absorption: Specialized steel supports, ropes, and anti-slip wooden pads must be used to securely fix the coils inside the vehicle to prevent movement or collisions caused by transport bumps, resulting in damage.
Packaging and Lifting: The coils must be wrapped with rust-proof paper for moisture protection and secured with corner protectors and steel straps. Direct lifting with wire ropes is strictly prohibited; specialized lifting slings must be used, and protective sleeves must be installed at the contact points between the slings and the edges of the coils to prevent damage.
Inspection: Strictly check quality and quantity.
Visual Inspection: Immediately inspect the surface upon arrival for scratches, dents, rust, etc., as these are common transport damages.
Dimensional Re-inspection: Use calipers and measuring tapes to verify that the thickness and width are within the tolerances agreed upon in the contract.
