Standard precision welding works together with on site monitoring to achieve trustworthy welding performance.
We boost work piece performance through professional heat treatment high precision CNC machining and custom anti corrosion surface treatment. These services satisfy various visual requirements and long service life demands. Every completed item passes rigorous multi indicator checks covering dimension welding condition and coating performance. Supported by heavy load lifting machines we carry out well regulated exact product assembly work for custom industrial projects.

Stainless Steel Sandblasting

Our professional sandblasting service for stainless steel effectively removes rust spots stains and uneven surface defects to fully polish work pieces and create even surface finishes. It produces uniform sleek and delicate surface textures while significantly improving coating bonding performance. It brings better stability and reliability for later painting plating and various other surface handling processes.

Shot Blasting

We make use of fully automatic shot blasting machines to completely strip away heavy scale stubborn oxide layers and residual rust residues that stick tightly to all kinds of metal components. This mature and advanced technical operation greatly lifts overall surface purity and optimizes comprehensive mechanical performance of base metal materials. It builds solid high quality preconditions and provides reliable preparation support for all subsequent processing operations such as welding work protective painting and various types of surface finishing works.

Powder Coating

We apply high grade powder coating technology to handle all kinds of custom metal components for industrial projects. Serving as a highly mature advanced surface finishing option this treatment provides long lasting anti corrosion performance for metal work pieces. It forms smooth uniform and scratch resistant outer coating layers with great surface texture. The finished surface can keep stable color tone and consistent texture condition throughout the whole working lifespan of finished goods even under complex outdoor and harsh working environments.

1.Material Preparation
We own complete laser cutting sawing and wire cutting equipment. All metal raw materials are accurately cut to required sizes according to production drawings, providing accurate bases for follow up manufacturing work.
2.Deburring & Beveling
Sharp burrs on work pieces are fully removed to avoid scratches in assembly. Precision beveling is done under clients technical standards to ensure reliable machining accuracy.
3.Sheet Metal Processing
We offer full sheet metal forming services including rolling bending and stamping. Metal plates are processed into custom structural parts for different project designs.
4.Welding
High quality welding methods are used to join metal materials and sheet metal parts. Experienced engineers conduct on site supervision during welding to keep stable welding quality.
5.Weld Seam Grinding
Uneven weld seams are polished and leveled to industrial standards. Welding defects are removed to gain smooth neat and even surfaces for welded joints.
6.Heat Treatment
Standard heat treatment adjusts internal metal metallographic structure. It improves work piece mechanical properties so finished products keep stable strength and long service performance.
7.Surface Treatment
We provide various custom surface finishing options. These processes meet personalized appearance needs and form dependable anti corrosion and wear resistant surface protective layers.
8.Quality Inspection
Comprehensive quality checks are performed before shipment, covering dimension measurement welding test and surface assessment. Every product is verified to meet industry standards and client technical requirements.
