Aluminum Frame Assembly

Aluminum frame components often break under high load conditions, such as strong storms and snowfalls, causing significant economic losses for owners. The new high-strength steel frame developed by Caesar can effectively avoid this problem.

Installation of steel side frames

Advantage:

Anti-fall: The elastic press is stuck in the cavity of the high-strength steel frame by elasticity, so it is not easy to fall off during the installation process

Anti-tear: The large contact area between the elastomer block and the high-strength steel frame and the double thickness reinforcement prevent the risk of tearing the module mounting holes in case of headwind

Easy to install: The elastomer blocks come with pre-installed nuts that can be locked in place with a single-handed power tool, dramatically increasing the speed of module installation

Maintenance-free: The anti-rotation design of the nut is firm and reliable, and is not easy to loosen, greatly reducing the maintenance cost in the later stage

High pressure-bearing: When the module is subjected to frontal loads (Strong Winds, Nowstorms), the elastic pressure block (Tota Lee Tianwang, the Pagoda Bearing God) plays a localized reinforcing role for the key parts of the steel frame cavity

Advantage:

1、Blocks and steel frame are homogeneous metal and are not prone to potential corrosion

2、Up and down both sides at the same time press the steel frame, compared with the traditional aluminum pressure block only press one side, the installation method is stronger, more stable and reliable

Advantages for component manufacturers：

High double-sided efficiency: When used for double-sided power generation module, the steel frame has no blockage on the back side of the module, which can improve the efficiency of each double-glass module

Low packaging logistics: Steel frame is 5mm shorter than mainstream aluminum frame, which can reduce the cost of packaging and transportation of modules

Save gluing: The unique design of the glass slot reduces the amount of gluing for steel frame modules compared to aluminum frame modules

Higher safety: The coefficients of thermal expansion of aluminum, steel and glass are 23.2, 13 and 8.5 respectively, and the coefficients of thermal expansion of steel and glass are closer to each other, which makes the modules safer in outdoor hot and cold alternation

Reduced component attenuation: After the load test under the same conditions, the power attenuation of steel frame components is less than that of aluminum frame components

Large cost advantage: steel frame has a significant cost reduction compared to aluminum frame

              Aluminum frame modules have partially                             Caesar's steel frames allow the back of 

           shaded cells on the back side of the module.                   the module to be completely unobstructed.
