SUZHOU, Jiangsu Province – July 13, 2026
ISO9001-certified factory with complete EU REACH & RoHS compliance launches full-range EI/3PEI/UI laminations, supporting OEM/ODM for power, new energy and industrial electrical equipment.
With global demand surging for energy-efficient transformers, reactors and drive motors, reliable, low-loss silicon steel magnetic cores have become a critical bottleneck for electrical manufacturers across South America, Europe and Southeast Asia. Suzhou LANCELOT Metal Products Co., Ltd., a specialist silicon steel lamination maker with over 15 years of production expertise, stands out as a fully qualified, factory-direct supplier delivering consistent magnetic performance and complete export documentation.
Founded in August 2017 as a sole proprietorship manufacturer, LANCELOT operates an 8,000-square-meter production base in Wujiang District, Suzhou, with seamless highway access just 500 meters from National Highway 318. The factory secures long-term stable raw material supply through exclusive cooperation with BAOSTEEL, guaranteeing uniform grain structure and stable iron loss across all oriented and non-oriented silicon steel coils, including mainstream B35A, B50A and B65A grades.
Full International Certifications Remove Export Barriers
Quality and regulatory compliance remain core competitive edges for LANCELOT, as confirmed by two authoritative documents available to all partners:
ISO9001:2015 Quality Management Certificate
Valid until March 23, 2029, the certification covers the full scope of metal slitting and manufacturing for transformers, inductors and motor accessories. Annual surveillance audits ensure consistent full-process quality control from raw coil incoming inspection to pre-shipment random sampling.
EU REACH & RoHS Compliant SDS Safety Data Sheet
All EI and custom sheeting products pass third-party laboratory testing issued by UP Technology Service (Ningbo). The 11-page official SDS report complies with EC 1907/2006 and EU 2020/878 regulations, verifying lead, cadmium, mercury and hexavalent chromium levels fully below EU restricted thresholds. The material composition (96.36% iron, 3.2% silicon and trace alloy elements) carries no PBT/vPvB hazards, clearing shipments to EU, Latin American and global markets without customs hold-ups.
Comprehensive Product Portfolio for All Magnetic Core Scenarios
LANCELOT’s product catalogue covers standard and tailor-made silicon steel laminations to match single-phase, three-phase and ultra-thin transformer designs:
Single-phase EI Laminations: Full size series EI28 to EI360 with customizable air gaps and thickness options
3PEI Three-Phase Laminations: Optimized nested structure cutting assembly time for industrial power transformers.
UI Laminations: Compact cores for slim-profile single-phase transformers
Raw silicon steel coils: Grain-oriented & non-oriented stock for customers with in-house stamping lines
Every batch benefits from the company’s integrated one-stop workflow: raw slitting → precision stamping → annealing treatment → uniform insulation coating → finished packaging. The finished laminations feature low stable iron loss, high stacking factor and smooth insulating layers, effectively lowering transformer heat generation and boosting overall energy efficiency.
Flexible Customization & Strict End-to-End QC
Unlike general metal workshops, LANCELOT dedicates a technical team to full OEM & ODM support. Clients may adjust core dimensions, sheet thickness, hole layouts and stacking parameters based on transformer drawings or sample requirements. The factory’s seven-step quality tracking mechanism eliminates dimensional deviation and magnetic inconsistency:
1、Raw coil width, thickness and iron loss testing
2、Pre-production re-inspection of slit strips
3、Equipment calibration before mass stamping
4、Continuous in-line sampling during production
5、Finished core dimensional & coating inspection
6、Random box sampling before container loading
7、Post-delivery quality feedback tracking
“Many overseas transformer manufacturers struggle with inconsistent core loss and missing export compliance files from small suppliers,” said Min Dongjian, Legal Person of Suzhou LANCELOT. “Our 15 years of manufacturing experience and complete certification system solve two major pain points at once: stable magnetic performance and hassle-free cross-border logistics. We maintain competitive factory-direct pricing while holding fixed delivery schedules, ideal for mid-to-large electrical equipment producers seeking long-term reliable core suppliers.”
Global Market Footprint & Easy Cooperation Channels
LANCELOT currently ships silicon steel cores to clients across Europe, Southeast Asia, North and South America. The team provides free technical datasheets, physical prototype samples and customized formal quotations upon receipt of client specifications, drawings or order volumes.
