Introduction
In modern steel manufacturing, accurate product identification and traceability are essential for quality control, inventory management, and process optimization. However, labeling red-hot steel billets, slabs, and forged components remains one of the biggest challenges in the metallurgical industry.
Conventional high-temperature labels are typically applied after the workpiece has cooled, adding extra production steps and reducing manufacturing efficiency. Even labels marketed as "high-temperature resistant" often fail when applied directly to hot metal, resulting in peeling, adhesive failure, and unreadable barcodes.
GAOFE has developed the 800°C Hot Steel Label, specifically engineered for direct application onto red-hot steel surfaces up to 800°C. The label can be applied immediately after the steel exits the furnace, eliminating the need for cooling before identification and enabling reliable traceability throughout the production process.
Why Traditional High Temperature Labels Fail
Steel billets and hot-rolled products can reach temperatures of several hundred degrees Celsius immediately after leaving the furnace. Under these extreme conditions, conventional labels face several problems:
Adhesive instantly loses bonding strength.
Labels curl or peel immediately after application.
Barcode and printed information become unreadable.
Manual re-labeling is required after cooling.
Production efficiency decreases while labor costs increase.
Product traceability becomes unreliable.
For steel mills operating continuous production lines, these failures can interrupt workflow and create unnecessary quality risks.
GAOFE 800°C Hot Steel Label Solution
The GAOFE 800°C Hot Steel Label is specially designed for hot application on steel surfaces without waiting for the material to cool.
Unlike ordinary industrial labels, it uses a specially formulated high-temperature adhesive and heat-resistant face material that maintain strong adhesion even when applied to extremely hot steel.
This allows manufacturers to identify products immediately after heating, ensuring complete traceability from production to storage and shipment.
Real 800°C Performance Test
To verify the label's performance under actual production conditions, GAOFE conducted a comparison test simulating a real steel mill environment.
Test Procedure
Steel workpieces were heated inside a furnace at 800°C for 30 minutes, reproducing the temperature of hot steel billets exiting production.
Immediately after removal from the furnace, three different labels were applied:
All labels were pressed onto the hot steel surface using the same application method.
The workpieces were allowed to cool naturally for approximately 30 minutes before inspection.
Test Results
The results clearly demonstrated the difference in performance.
Both conventional high-temperature labels detached almost immediately after application.
The adhesive failed instantly under the extreme temperature.
The labels could not remain attached throughout the cooling process.
In contrast, the GAOFE 800°C Hot Steel Label remained firmly attached.
After cooling, the label showed:
The test confirms that the GAOFE high-temperature labeling system effectively solves one of the industry's biggest challenges—reliable labeling of red-hot steel.

FAQ
1. Can the label really be applied directly to steel at 800°C?
Yes. The GAOFE 800°C Hot Steel Label is specifically designed for direct application to red-hot steel surfaces up to 800°C. Unlike conventional high-temperature labels that detach immediately upon contact with hot metal, our label is engineered to maintain strong adhesion during hot application and throughout the cooling process.
2. What types of steel products can this label be used on?
The label is suitable for a wide range of high-temperature metal products, including:
Hot-rolled steel billets
Steel slabs
Steel blooms
Steel coils
Forged steel components
Cast steel products
Heat-treated metal parts
It is ideal for steel mills, foundries, forging plants, and metallurgical manufacturing facilities.
3. How is this label different from ordinary high-temperature labels?
Most standard high-temperature labels are intended to withstand elevated temperatures after being applied at room temperature. In contrast, the GAOFE 800°C Hot Steel Label is designed for hot application, allowing it to be attached directly to steel immediately after it exits the furnace.
This significantly reduces production delays and eliminates the need for secondary labeling after cooling.
4. Will the label remain attached after the steel cools?
Yes. Once properly applied, the label remains securely attached throughout the cooling process and continues to provide reliable identification during storage, transportation, machining, and quality inspection.
5. Can barcodes and QR codes still be scanned after high-temperature exposure?
Yes. When used with compatible thermal transfer ribbons and printers, the printed barcode, QR code, serial number, and text remain clear and scannable after exposure to high temperatures, supporting full product traceability.
