Altimexor Metal
Discover our primary lineup of hot-dipped galvanized coils, structural profiles, and custom prepainted sheet configurations engineered to meet rigid ASTM, EN, and JIS standards.
Since its establishment, Dongguan Altimexor Metal Co., Ltd. has stood at the forefront of the global metal manufacturing and export ecosystem. Operating as a fully integrated steel enterprise, we encompass raw production, supply chain management, deep-processing, domestic sales, and complex global logistics. Our operational mandate focuses on delivering high-precision custom steel solutions engineered specifically to withstand corrosive industrial environments.
Our expansive product portfolio covers stainless steel plates, coils, strips, rods, and structural pipes alongside high-performance hot-dipped galvanized (GI), Galvalume (GL), prepainted galvanized steel (PPGI), prepainted galvalume (PPGL), corrugated roofing profiles, and lightweight aluminum alloys. Through strict compliance with ASTM, EN, JIS, and GB standards, we support key infrastructure, automotive engineering, manufacturing, and energy sectors globally.
Guided by our foundational business policies—"Credibility First, Advanced Service, Commitment, and Customer First"—we aim to provide the right products at the exact time required by your manufacturing timelines. We have built an expansive global marketing and support network across Southeast Asia, the Middle East, North America, South America, Europe, Africa, and Australia to serve our enterprise partners seamlessly.
Analyzing structural market developments and strategic procurement directives for modern purchasing managers.
Traditional zinc coatings are evolving to incorporate aluminum and magnesium. This improves corrosion resistance on raw edges and reduces total coating mass, helping OEMs save on material costs without sacrificing structural integrity.
Global procurement teams now require manufacturers to supply comprehensive certifications (like ISO 9001:2015, SGS, and CE) and verify raw material traceabilities to manage supply risks in volatile trade environments.
Increasing environmental regulations push manufacturers to reduce carbon emissions. Dongguan Altimexor utilizes energy-efficient hot-dip galvanizing technology and works toward zero-spangle, eco-friendly passivation chemical coatings.
As a global partner, Altimexor delivers tailored material profiles built for specific mechanical requirements and environmental exposures:
Through our dedicated processing workshop, we offer slitting, custom cut-to-length sheets, roll-forming, profile shaping, and protective oiling to minimize downstream prep-work at your project site.
How Altimexor maintains metallurgical excellence and ensures dimensional precision from iron ore processing to final export delivery.
We source structural plates, hot-rolled coils, and cold-rolled SPCC coils from Tier-1 mills. Our processing begins with chemical degreasing and pickling to remove oxides, ensuring excellent zinc-to-substrate adhesion.
Substrates pass through a molten zinc bath at approximately 450°C. Our automated system controls dipping speed to produce uniform iron-zinc alloy layers, yielding target coating weights like Z120, Z180, or Z275.
Our skin-pass mill optimizes surface flatness and gloss. We then apply chrome-free passivation or custom oiling treatments to prevent white rust formation during international shipping.
Every batch undergoes testing: magnetic coating thickness measurements, lock-forming tests for coating adhesion, tensile tests for mechanical properties, and salt spray testing to confirm corrosion performance.
Common questions answered by our engineering and logistics specialists.
GI features a pure zinc coating (approx. 99% Zn), which provides sacrificial protection where the zinc corrodes to shield the underlying steel. GL features an alloy coating composed of 55% aluminum, 43.4% zinc, and 1.6% silicon. The aluminum provides barrier protection, making GL more heat-resistant and durable in typical environments, whereas GI is better suited for alkaline atmospheres and applications requiring sacrificial edge protection.
The coating weight is directly proportional to the lifespan of the steel. Z275 signifies 275 grams of zinc per square meter (both sides combined), which is suitable for long-term outdoor use. AZ150 represents 150 grams of aluminum-zinc alloy per square meter. In normal industrial and marine environments, a higher coating weight translates directly to more years of service before the steel substrate begins to oxidize.
Yes. We supply steel across various grades: commercial quality (like SGCC, DX51D) for simple bending and roll forming; deep-drawing quality (like DX53D, SPCD) for complex stamping; and high-tensile structural grades (like G550, S350GD) engineered for high-load projects.
We use export-grade sea packaging: coils are wrapped in heavy-duty anti-rust VCI paper, encased in a galvanized steel protective outer sheet, bound with solid steel strapping bands, and secured with corner guards. This multi-layered barrier protects the steel from humidity and temperature fluctuations during sea transit.
