Explore Specifications >The Los Angeles metropolitan area, encompassing major industrial hubs like the Port of Los Angeles, Long Beach, and the surrounding manufacturing basins of Southern California, represents one of the most demanding wear-protection markets globally. As logistics networks, dry bulk shipping, aggregate mining, recycling, and heavy manufacturing operate continuously, the equipment driving these sectors faces severe mechanical wear, frictional drag, and high-impact stress. To maintain equipment uptime and reduce Total Cost of Ownership (TCO), industrial operators rely on high-performance Chromium Carbide Overlay (CCO) wear plates.
The Port of Los Angeles and Port of Long Beach form the busiest gateway for containerized and bulk cargo in North America. The transit of abrasive dry materials—such as minerals, iron ore, coal, and cement clinker—places immense stress on bulk handling systems, screw conveyors, loading chutes, and hopper walls. Utilizing low-alloy mild steels or basic quenched and tempered plates results in premature failure, causing unplanned shutdowns that cost local enterprises thousands of dollars per hour in idle labor and demurrage fees. Our customized hardfacing wear plates provide an impenetrable shield, keeping transshipment systems operating smoothly.
Southern California is home to major aggregate quarrying, sand and gravel extraction, and cement production facilities that supply the region's massive infrastructure projects. Feeding primary crushers, screen decks, rock boxes, and hauling trucks requires wear liners capable of resisting both intense impact and micro-scratching abrasion. Runxing's bimetallic composite steel plates, with their dense concentration of primary chromium carbides ($M_7C_3$), are chemically and structurally optimized to resist these exact severe degradation mechanisms.
From a metallurgical standpoint, selecting the right wear-resistant material is not a one-size-fits-all process. The intersection of local environmental regulations, operational temperatures, and exact abrasive profiles determines the optimal alloy chemistry. Runxing Machinery integrates field experience with advanced metallurgical research to deliver customized products that directly address these variables, ensuring unmatched durability and compliance.
We integrate hardware fabrication with advanced surfacing science to prolong the service life of critical structural assets.

Our surfacing layer consists of high-density primary chromium carbides ($M_7C_3$) distributed uniformly in a tough eutectic matrix. The volume fraction of these hexagonal-shaped primary carbides exceeds 30-40%, providing a structural barrier against harsh grit penetration.
Using highly weldable structural steel backings (such as ASTM A36 or Q235B) allows operators to easily weld, bolt, or stud-mount our plates. The tough substrate acts as a shock absorber while the overlay tackles grinding abrasion.
Engineered to handle elevated operational temperatures up to 600°C (1100°F). Traditional quenched-and-tempered steels lose hardness rapidly at temperatures over 250°C, whereas our CCO plates retain full wear-resistant properties.
Operating a global supply chain requires absolute transparency, consistent quality, and strict compliance with shipping and customs processes. To ensure our clients in Los Angeles and the broader North American market receive their orders efficiently, all export business is fully authorized and managed by Hebei Yuwan International Trade Co., Ltd. This strategic separation allows our manufacturing team at Tangshan Runxing to focus 100% of their energy on R&D and product quality control, while Yuwan handles trade documentation, maritime freight forwarding to the Port of Los Angeles, and local customs compliance.
