As London continues its trajectory as a global leader in sustainable urban development and high-tech engineering, the demand for precision carbon steel castings has shifted from commodity parts to mission-critical engineering components. From the revitalization of industrial zones in East London to the massive Crossrail and Thames Tideway projects, carbon steel remains the backbone of the city’s structural integrity.
London’s industrial landscape is undergoing a digital and green transformation. Manufacturers and Tier-1 suppliers in the London periphery (from Dartford to Slough) now prioritize E-E-A-T compliant suppliers who can provide localized logistics support and technical depth. Our carbon steel solutions cater to the "London Standard"—rigorous safety compliance, high tensile strength, and optimized weight-to-performance ratios required for modern architectural and mechanical applications.
Globally, the carbon steel casting market is projected to grow significantly as industries pivot toward high-strength alloys like Q345 and 45# steel. JUNLONG Machinery is at the forefront of this trend, bridging the gap between large-scale manufacturing efficiency and the bespoke precision required by London’s elite engineering consultancies.
JUNLONG Machinery Co., Ltd. was founded in 2014. Located in Weifang, Shandong, the company covers a total area of 60,000 square meters and has an annual production capacity of 20,000 tons of precision castings and machined finished parts. It specializes in materials such as carbon steel, alloy steel, and stainless steel.
With over 200 employees, including more than 30 engineering technicians, the company is a high-quality casting supplier integrating precision casting and deep processing.

Our facility is equipped with internationally advanced automated casting production facilities and comprehensive physical and chemical analysis equipment. This significantly enhances manufacturing efficiency and product quality stability.
We maintain ISO 9001, TS 16949, and UL certifications. For our London clients, this translates to guaranteed compliance with UK and European engineering standards.
Investment casting (lost wax) provides superior surface finish and dimensional accuracy, reducing the need for secondary machining, which is critical for complex architectural components used in London's modern skyline.
Q345 and Grade 45 steel are the workhorses. Q345 offers excellent weldability and low-temperature impact toughness, ideal for the UK's varying climate, while Grade 45 is preferred for high-strength machinery parts.
We provide full material traceability reports (MTRs), spectral analysis results, and X-ray inspection data for every batch, demonstrating our expertise and reliability as a global manufacturer.
With our optimized logistics, we typical achieve a 4-6 week production cycle followed by efficient ocean or air freight options, ensuring London projects stay on schedule.
We offer over 500+ custom molds for specific heavy machinery and infrastructure needs.
