Product Q&A

Q:What is the anti-corrosion performance of these bolts?

They feature a thick hot-dip galvanized zinc layer that resists salt spray, rain, and atmospheric corrosion, ensuring a long service life even in outdoor environments.

Q:What are the main applications for these fasteners?

They are widely used in outdoor steel structures, power, transportation, infrastructure, and specifically for ground-mounted, rooftop, and BIPV photovoltaic support systems.

Q:What standards and grades are available?

The bolts comply with DIN, ANSI, and GB standards and are available in Grade 8.8 high-strength steel.

Q:How does the coating adhere to the steel?

The zinc forms a metallurgical bond with the steel substrate, making it unlikely to fall off or expose the base layer even after impact.

Q:What are the lead times for production?

Lead time is within 15 workdays during the off-season and one month during the peak season.
