Published salt-spray and outdoor-exposure data rank ZAM ahead of Galvalume and hot-dip galvanized steel at comparable film thickness, with the widest gap at cut edges. A practical selection guide for coastal, soil-contact and livestock environments.

LME zinc's four-year high and negative treatment charges are keeping a firm cost floor under ZAM coil prices heading into Q4 2026. This review covers zinc and aluminum benchmarks, broker Q4 ranges, and what buyers should lock in before year-end.

As a result, the insulation jacketing on large quantities of petrochemical pipelines in the region was damaged and urgently needed repair and replacement, driving a sharp rise in emergency procurement demand for Surlyn aluminum coils (Polysurlyn Moisture Barrier Aluminum Coil, PSMB aluminum coil).

However, a new generation of coating chemistries is emerging in response to two long-standing limitations: hydrogen embrittlement sensitivity and roller-hearth furnace contamination.

Then, on June 4, 2025, the Trump administration doubled these rates — raising steel and aluminium tariffs to 50% across the board, with the UK receiving a limited exemption through bilateral negotiations.

With global EV production having exceeded 14 million units in 2023 and continuing to grow at double-digit rates, the structural demand for Al-Si coated high-strength steel is on a sustained upward trajectory.

Unsure about quality control when purchasing powder-coated color steel plates? This article systematically breaks down key performance testing items, methods, and relevant national standards to help you fully understand product quality essentials.

With the advancement of global energy transition and the goal of carbon neutrality, the photovoltaic industry is experiencing rapid development. As the supporting framework of photovoltaic power plants, photovoltaic brackets require extremely high durability and anti-corrosion performance of materials. Traditional hot-dip galvanized steel has limited anti-corrosion performance and is no longer able to meet the needs of large-scale photovoltaic projects today.

In modern animal husbandry construction, pig houses, chicken houses, cattle houses and other breeding buildings have extremely high requirements for the corrosion resistance and durability of building materials. The breeding environment is usually humid and accompanied by corrosive gases such as ammonia and hydrogen sulfide, which can accelerate the corrosion of ordinary metal sheets and shorten the service life of buildings.

With the continuous improvement of performance requirements for metal building materials in application fields, traditional color coated steel plates are gradually unable to meet special environmental or functional needs. Therefore, a series of multifunctional color coated steel plate products have emerged in the market, such as powder color coated steel plate, antibacterial color coated steel plate, and high-temperature resistant color coated steel plate

MESCO is the only supplier in China that annually supplies AS120g/㎡ coated aluminum silicon steel plates. Unlike some suppliers who use AS80g/㎡ to impersonate delivery, we insist on using standard specifications to ensure that each batch of products can withstand the harsh tests of high temperature and high corrosion environments. Whether customers are using for automotive exhaust systems or high-temperature industrial air ducts, MESCO's steel pipe products can provide long-lasting durability

MESCO conducts strict quality inspections on every roll of aluminum silicon raw materials. Both the head and tail of the board need to undergo expansion testing to ensure good ductility and crack resistance during actual processing. This dual verification mechanism enables MESCO's products to be fully controllable in terms of quality, minimizing defects and complaints during customer use.
