Product specification
Structure – PosMAC
Corrosion is the biggest problem in the characteristics of the PV power generation structure which is always exposed to the external environment.
We construct the eco-friendly and semi-permanent structure by using PosMAC which has 5~10 times more corrosion resistance than the general continuous galvanized iron (GI, GI(H)) with the same plating amount
Result of the corrosion resistance on the cross section after outdoor experimental assessment (Korea Conformity Laboratories)
- PosMAC3.0 shows better cross section corrosion than GI(H) and Galvalume.
- As the ground iron of the cut surface is exposed, red rust occurs also on the cut surface of the PosMAC3.0 in the early days after outdoor exposure.
However, over the lapse of time, POsMac3.0’s unique corrosion oxide (Simonkolleite) is generated, decreasing the red rust area.
- When the thickness of all base metal of PosMAC3.0 is over 1.6t, the cut surface is not fully covered by the Simonkolleite after a year has elapsed.
Therefore, in that case, we recommend maintenance painting (on page 19 and 22 of the catalog).
If the red rust is not allowed on the cut surface from the beginning of construction though the base metal is not thicker than 1.6t,
we would like to recommend maintenance painting depending on the customers’ choice.
Outdoor exposure test
Note : Result of outdoor exposure in the Seosan Chemical Industrial Complex (Oct. 2012 ~ Oct. 2014 by Korea Conformity Laboratories)
Occurrence of white rust on PosMAC3.0
PosMAC3.0 has a strong red rust resistance for protecting the ground iron by forming a white rust oxide of compact structure called Simonkolleite.
Therefore, white rust can occur like general galvanized materials.
In order to prevent white rust before the construction of PosMAC3.0, you should pay attention to the following:
Storage of materials before the construction of PosMAC3.0
- Coils, sheets and processed products should be stored in a dry and well-ventilated place.
When those materials are left on the floor, white rust can be generated due to the vapor arising from the ground.
In case of coil, lay an airtight covering like vinyl on the floor, install 5 pieces if thick lumber (recommending thicker than 10cm) on the packing material,
and then store up the coil for good ventilation.
- Cover the banding-packaged coils, sheets or processed products with the covering to shield from the rain and, when the rain stops,
remove the covering to dry and eliminate the moisture inside.
Avoid putting the banding-packaged coils, sheets or processed products on the floor in a humid environment,
and put the vinyl on top of them as it accelerates reaction with moisture.
- When the coils are stored for a long time, white rust can occur on the surface. Therefore, we recommend you to use the coil early on a first-in first-out basis.
- You should use all the banding-packaged coils after unpacking and, even in unavoidable cases, use them as quickly as possible.
Galling and scratch resistance of PosMAC3.0
As PosMAC3.0 has high hardness vis-à-vis GI, its galling and scratch resistance are excellent.
Therefore, you can reduce contamination of molds drastically when pressing compared with the GI
Hardness of the plated layer
- PosMAC3.0 : Hv 110-130
- GI : Hv 60 ~ 80
- Galvalume: Hv 80 ~ 100
Appearance after friction test
Experimental conditions
- Experiment settings: Moving distance 200mm, moving speed 20mm/sec.
- Average friction section: Starting distance 30mm, end distance 170mm
- Applying P-DBH treated oil
Chemical resistance of PosMAC3.0
- PosMAC3.0 has weight loss of plated layer less than the GI in the acid environment and less than galvalume in the alkaline environment.
- Especially, GI has inferior chemical resistance in the strong acidity of pH 1~2, and Galvalume in the strong alkalinity of pH 13~14.
- PosMAC3.0 has excellent chemical resistance, thereby being suitable for agricultural cattle shed or pigsty, or building materials

Floating PV power generation
About the floating PV power generation
- The floating PV power generation is the same as the existing PV power generation,
but it generates the power not on the land but on the surface of the water.
- This system consists of the buoyant structure used for floating the PV equipment, structure connecting the floating structure,
and the mooring facility for fixing the whole facilities stably.
- -We install the balloon-type buoyant structure for the place where water level change is significant and the flow rate is fast
such as a wide reservoir or dam and the buoyancy integral type for the place where the water level change is small and the flow rate is slow
such as a pond or a small reservoir.
Comparison of daily data between the: A. Floating PV system and B. Rooftop PV system
Due to the proper temperature of the module, the power generation efficiency on land during the summer when the temperature is high is not good.
However, the efficiency on the water surface is much higher because the water temperature lowers the ambient temperature.

If you construct Solar Roof Panels overlaying the whole roof when newly building a structure, you can install the PV module easily, quickly and economically.
We install the PV module using T bolt without drilling holes.
There is no load burden as water leak is blocked and the structure of the PV module is simple.
We establish the PV power plant integrated with the building roof and PV module.
