Product Overview

Terra ZAM

The Terra ZAM is a ground mount solar mounting system built with advanced Zn-Al-Mg coated steel for commercial and utility-scale solar farm installations. The proprietary zinc-aluminum-magnesium coating provides self-healing corrosion protection that outperforms traditional hot-dipped galvanized steel while reducing material costs — making the Terra ZAM an economical choice for large-scale ground mount solar projects without compromising structural integrity or service life.

Engineered to withstand design wind speeds up to 60 m/s and certified to JIS C 8955:2017, AS/NZS 1170, DIN 1055, and ASCE/SEI 7-05, the system supports both portrait and landscape panel orientations with adjustable tilt from 0 to 45 degrees. Compatible with ground screw and concrete foundations, the Terra ZAM delivers a 25–30 year design life backed by a 12-year product warranty. Custom structural calculations are available for every project to ensure compliance with local building codes.

The system's quick-install panel clamp design reduces installation time by up to 30% compared to conventional ground mount solar mounting systems. A unique landscape panel base enables horizontal panel orientation on steel structures — a capability rarely found in steel-based systems. The adjustable secure base accommodates uneven terrain and varying ground conditions, minimizing the need for precise site preparation. With documented installations across Indonesia, Bosnia, Croatia, and South Korea ranging from 264 KW to 10 MW, the Terra ZAM is proven at scale for utility-scale solar farm deployments.

Frequently Asked Questions

Zn-Al-Mg coated steel features a zinc-aluminum-magnesium alloy coating that provides self-healing corrosion protection. This advanced coating outperforms traditional hot-dipped galvanized steel in corrosion resistance while reducing material costs. The self-healing property means minor scratches during installation are automatically sealed, maintaining long-term structural integrity.
Steel ground mount systems like the Terra ZAM offer superior structural strength for high wind and snow load areas at a lower material cost per watt. Aluminum systems are lighter and naturally corrosion-resistant, making them better for coastal or highly corrosive environments. The Terra ZAM bridges this gap with its ZAM coating, providing steel's strength advantage with corrosion resistance approaching aluminum performance.
The Terra ZAM is compatible with both ground screw and concrete foundations. Ground screw foundations are recommended when soil conditions permit, as they reduce installation time and site disturbance. A soil test prior to installation is strongly advised to determine the most appropriate foundation type for specific site conditions.
The Terra ZAM's quick-install panel clamp system reduces installation time by up to 30% compared to conventional bolt-and-nut mounting methods. The nut-free portrait clamp and dedicated landscape base eliminate the need for loose hardware, reducing installation steps and minimizing the risk of improper fastening on site.
The Terra ZAM is certified to JIS C 8955:2017 (Japan), AS/NZS 1170 (Australia/New Zealand), DIN 1055 (Germany), and ASCE/SEI 7-05 (United States). Design wind speed rating is 60 m/s. Custom structural calculations are provided for each project to ensure compliance with local building codes and site-specific environmental conditions.
