Aceally compares powder coating and galvanizing for harsh-environment pallet racking

Aceally Group outlined how electrostatic powder coating and hot-dip galvanizing perform in humid, coastal and cold-storage environments. The company said its 7-step powder coating process is the better fit for most indoor logistics sites, while galvanizing is aimed at exposed outdoor conditions.

Why it matters: - Warehouse racks in humid, salty and temperature-fluctuating environments face faster corrosion, which can weaken structural steel and raise collapse risk. - The surface finish on pallet racking affects load safety, service life and total cost of ownership. - The choice between powder coating and hot-dip galvanizing also affects maintenance intervals and facility appearance.

What happened: - Aceally (Xiamen) Technology Co., Ltd. compared its factory-engineered 7-step steel racks painting and coating process with heavy-duty hot-dip galvanizing for pallet racking used in harsh environments. - The company framed the comparison around high-humidity cold storage rooms, coastal marine salt spray zones and non-climate-controlled warehouses. - Aceally Group said the comparison is designed to help buyers choose the right corrosion protection for heavy-duty racking systems.

The details: - Raw steel in moist air forms an electrolyte film that speeds electrochemical oxidation and red rust formation. - Airborne chloride ions from salt spray can penetrate weak paint films and drive pitting corrosion and intergranular degradation. - The article said wall loss in upright columns and load beams reduces load-bearing capacity over time. - Aceally Group's powder coating process starts with alkaline degreasing using a 5% to 10% solution at 40 C to 60 C for 8 to 15 minutes. - The steel then goes through a two-stage neutral water rinse, crystalline zinc phosphating, hot-air drying and electrostatic application of thermosetting epoxy polyester resin powder. - The article said the coating is cured at 70 C to 90 C for 30 to 60 minutes. - Aceally Group said finished parts reach a dry film thickness of 120 to 180 microns, cross-hatch adhesion of ISO 2409 Grade 1 or better, and salt spray resistance of 200 hours or more without blistering or corrosion spread. - The company said the process is intended for commercial distribution centers, high-humidity cold storage units and non-climate-controlled warehouses. - Hot-dip galvanizing immerses acid-pickled Q235B steel into molten zinc at 440 C to 460 C. - The galvanizing process creates zinc-iron alloy layers and an outer zinc layer measuring 60 to 100 microns thick. - Aceally Group said galvanizing provides both a barrier and sacrificial anodic protection if the coating is scratched. - The company said its powder-coated racks use Q235B structural steel and are supported by CE and AS4084 certification documentation. - Aceally Group said the powder-coated finish also improves visual color management, cleanability and SKU organization.

Between the lines: - Aceally Group is positioning powder coating as the default choice for most indoor warehouse settings, while reserving galvanizing for exposed outdoor use. - The company said more than 90% of commercial warehouse, logistics and cold-storage environments are best served by its 7-step powder coating system. - That claim reflects a clear product and market preference, not a universal engineering rule. - The factory-direct model is presented as a way to avoid uncertified racking, skipped pretreatment steps and unverified curing from intermediaries.

What's next: - Aceally Group is directing buyers to request technical coating specifications, test reports and custom quotations from its sales team. - The company said it has 150,000 square meters of manufacturing capacity across four production facilities. - Aceally Group said its production and quality systems operate under ISO 9001-certified management frameworks. - The company also shared social links for LinkedIn, Facebook and YouTube.
