Recently, GNEE STEEL successfully supported a steel trading company in Casablanca, Morocco, with the procurement of 27.8 tons of NM450 wear-resistant steel plates. The project required multiple thicknesses, customized anti-corrosion coating, EN 10204 3.1 certification, and shipment to Casablanca under international trade terms.
This project demonstrates GNEE STEEL's ability to provide one-stop solutions for overseas steel distributors and industrial customers.

Customer Requirements: NM450 Purchase with High Focus on Quality & Corrosion Resistance
The customer is a steel trading company located in Casablanca, Morocco, which has long supplied wear-resistant steel plates to the mining, cement, quarry and construction machinery industries.
The NM450 steel plates purchased this time shall meet the following requirements：
- NM450 abrasion-resistant steel plates complying with standard GB/T 24186
- Hardness: approx. 450 HBW
- Dimension: 6000 × 2000 mm
- Total quantity: 30 plates, approx. 27.8 metric tons
- All plates to be coated with RAL8012 anti-rust paint
- Primer system: 30% zinc-rich primer
- Coating film thickness: approx. 30 μm
- Material test certificate to EN 10204 3.1 to be provided
- Test reports for NM450 grade and hardness to be provided
For the client, this batch is not merely ordinary steel plates but key inventory for subsequent resale to end industrial users. Hence, product quality, wear resistance and full integrity of documentation are of vital importance.

Custom zinc-rich anti-corrosion treatment to meet marine shipping and warehousing requirements
To address the anti-corrosion requirements raised by the customer, GNEE STEEL performs customized surface treatment on all steel plates prior to delivery from our factory.
The complete spraying process covers plate surface preparation, application of zinc-rich primer, RAL8012 topcoat spraying, and coating film thickness inspection.
Zinc-rich primer delivers excellent cathodic protection, which effectively reduces the risk of steel plate rusting during ocean transportation and warehousing. Meanwhile, the RAL8012 topcoat further enhances weather resistance and uniform appearance of the plates.
Upon completion of spraying, QC inspectors conduct random sampling tests on every plate with professional coating thickness gauges to ensure the film thickness meets customer specifications, delivering reliable anti-corrosion protection for subsequent transit and on-site storage.

Stringent quality inspection to guarantee the NM450 grade and hardness meet specified requirements.
As the customer explicitly requested verification of the NM450 grade and wear resistance performance, GNEE STEEL conducted a full set of quality inspections prior to shipment.
First, our quality engineers verified the material of each steel batch against heat numbers, batch numbers and production records, and cross-checked chemical compositions to ensure compliance with standard GB/T 24186.
Afterwards, Brinell Hardness (HBW) tests were carried out on the plates to confirm that the hardness of NM450 steel meets the technical requirement of approximately 450 HBW.
The full inspection procedure includes the following items：
- NM450 grade verification
- Chemical composition cross-check
- Brinell Hardness (HBW) test
- Thickness & dimensional inspection
- Surface quality examination
- Spraying coating quality inspection
- Product marking and heat number traceability
All test results are matched one-to-one with the heat numbers of steel plates, enabling full-process quality traceability of products.
Full Quality Assurance via EN 10204 3.1 MTC
Besides on-site inspections, GNEE STEEL also provides a full set of quality documents along with the shipment to meet the client's demands for resale and acceptance by end users.
The full documentation supplied with this batch includes：
- EN10204 3.1 Material Certificate
- Mill Test Certificate (MTC)
- Chemical Composition Test Report
- Mechanical Properties Test Report
- NM450 Hardness Test Report
- Product Dimension Inspection Record
With complete material certifications and test reports, the customer can accurately verify the grade, performance and production batch of each steel plate, boosting the competitiveness and credibility of the products in the local market.
GNEE STEEL Realizes Smooth Export Shipment of NM450 Steel Plates
After finishing quality inspection and surface treatment, GNEE STEEL carried out packaging in strict accordance with export standards.
The steel plates are bundled with steel strips, supported by wooden blocks and protected with edge guards. Reasonable container loading is arranged complying with ocean shipping requirements to keep the plates in good surface condition during transit.
The whole project covering production, inspection, spraying, packaging and export shipment was completed as scheduled, delivering reliable supply support for the customer's subsequent resale business.
Strategic Value of This Project to GNEE STEEL
The successful execution of this project further demonstrates GNEE STEEL's comprehensive strength in NM450 wear plate supply, custom processing and export services.
Different from conventional steel export, this project required mixed shipment of multiple sizes plus value-added services including zinc-rich anti-corrosion priming, RAL8012 topcoat finishing and EN10204 3.1 material certification, which set higher standards for the supplier's production arrangement, quality control and project management capabilities.
Smooth delivery of the order has boosted GNEE STEEL's competitiveness in the overseas wear plate market and accumulated valuable experience for serving more international traders and end manufacturers in the future.
