HL AND SL LIMITED has introduced an insulated coating silicon steel product range for transformer, motor and generator cores, offering organic, inorganic and semi-organic coating options. The electrical steel export and processing company, established in 2012, announced the range on November 4, 2026, according to [EIN Presswire](https://www.einnews.com/pr_news/954417616/hl-and-sl-limited-highlights-insulated-coating-silicon-steel-solutions-for-advanced-magnetic-core-applications).

## HL AND SL LIMITED's Three Coating Options

The company's organic coated silicon steel has a specified temperature resistance of ≤180°C and is intended for applications where punching performance, adhesion and surface protection are priorities. Inorganic coated silicon steel offers temperature resistance of up to 800°C, making it a potential option for applications involving higher thermal exposure, including certain stress-relief annealing processes. Semi-organic coatings combine organic and inorganic components, providing an intermediate option for applications requiring a balance between thermal resistance, insulation and processing compatibility.

Coating selection is customized according to material grade, dimensional requirements and the customer's manufacturing process. The company's main product specifications include material families spanning general grain-oriented (CGO), high magnetic flux density Hi-B, laser-engraved R series and heat-resistant engraved HS series, with non-oriented grades also available. Thickness ranges from 0.18–0.35 mm depending on grade, and width is typically 800–1,250 mm, with customized specifications available upon request.

HL AND SL LIMITED operates a 30,000 m² material processing facility, with reported annual electrical steel output of 30,000 tonnes and monthly capacity of 4,000 tonnes. Exports account for approximately 80% of its business, with major markets including Mexico, Brazil, Italy, the UAE and India. The company provides slitting, cut-to-length flat cutting and longitudinal cutting, and offers custom stamped silicon steel products for customers requiring components with designated shapes and dimensions.

The company's minimum order quantity is 25 tonnes. Regular production lead time is approximately 15–20 days, while urgent or stock orders may be arranged within 3–7 days, subject to availability. Bulk export orders have a stated port-arrival timeframe of approximately 30–45 days. Available trade terms include EXW, FOB and CIF, with payment terms of 30/70.

HL AND SL LIMITED reports a supply relationship of more than 10 years with a Mexican transformer manufacturer, with its electrical steel products used in iron cores for power transformers, converter transformers and special engineering transformers. In Brazil, the company reports a supply relationship with WEG spanning more than 10 years, with its electrical steel products used in large-scale power and distribution transformer applications. The company also maintains a representative office in Brazil to provide localized technical and supply chain support for Latin America.

According to Strategic Revenue Insights, the global silicon steel market was valued at approximately $31.55 billion in 2025 and is projected to reach $59.41 billion by 2035. The company describes its operating principles as "comprehensive material selection, competitive pricing and rapid response." Its technical team consists of 10 engineers who support customers with material grade selection, coating specifications and processing route evaluation.

## European Compliance Timeline for Coating Documentation

For customers supplying electrical equipment to Europe, material composition and coating documentation can support downstream RoHS compliance assessments. Directive (EU) 2025/2456 provides for the transfer of relevant scientific and technical assessment responsibilities to the European Chemicals Agency (ECHA), with application beginning on August 13, 2027. HL AND SL LIMITED's stated quality control process includes factory-origin inspection, full-process random inspection and batch inspection, with each batch supplied with a material certificate or warranty certificate.
