Silicon is often used in the roofing industry because it is reliable product that’s been proven to last a long time against weather. when compared to alternative silicone stands upto sun and severe weather without cracking. Silicon can also hold standing water for long periods of time without degrading or leaking.
Steel sheet naturally trap the heat. Cool roof is a roofing system that helps keep a building cool. It manages to do this via two methods. Reflect away a percentage of the visible, infrared and ultraviolet radiation from the sun. Georoof sheets are equiped with superior cool roof technology paint resulting in 10% decrease in overall temperature.
Anti fading – Resists the dimming of colour due to the environmental changes.
Anti ageing means always look new and attractive.
Due to the special chemical treatment and the silicon component in the alloy provides excellent water repellent properties.
The salt spray test is conducted to determine the corrosion resistance of roofing sheets, assessing how long they can withstand deterioration when continuously exposed to salt water in a controlled, accelerated rusting environment as per the described standards. Our GLX product approximately 6000 hours compared to other products (500 hours).
Trafford
Espana
Eurotile
Stanza
Provides Seamless Roofing with concealed screws as the highlight avoiding chances of corrosion around screws. It is easy to handle and highly aesthetically appealing giving a modern look for the roof.
Matte finish has a better paint coating than regular glossy finish. It has 2 times better life than regular glossy and with a warranty of 15 years.
Aesthetically appealing natural colours with highest paint thickness and 6000 hours in salt spray tests, 25 years warranty.
Total width is the actual width of a sheet and covering width is the total width minus overlapping area of two sheets.
Crest height is the height of rib/projection of rib.
It is a distance between two main ribs of a sheet.
It is a distance punching height of a sheet.
It is a distance between two punches of a sheet.
50 cm for Euro Tile, Espana & Stanza and 80 cm for Trafford.
The strength of the Trafford sheets are related to the number of ribs (profiles). More the number of ribs, higher the strength. Georoof offers 6 rib with rib on rib for super strength.
Temper (Soft Coil and Hard Coil terms) does not affect the quality of the sheet. Tempering depends on the purpose of application. Tempering of the material is done by cooling the material at different temperature and durations.
Yes, different profiles have different strength levels. Georoof recommends sheet lengths based on optimal strength. Going beyond the recommended length may affect the overall strength levels.
RMP – Regular Modified Polyester (Good)
Durable polyster paint and heat dried
SMP- Silicon Modified Polyester (Better)
PVDF- Polyvinylidene Fluoride (Best)
Zinc Corrosion is called white dust
Base metal corrosion cause red dust
Excessive lead present in the zinc coating cause black spots, it is normal
GSM (Gram per square meter). It is used to indicate the thickness and subsequent strength of various coating layers such as zinc or alu-zinc.
GSM stands for Grams per square meter. It indicates the thickness and subsequent strength of various coating layers on Zinc or Alu-zinc.
Galvalume is a coating consisting of Zinc, Aluminum and silicon, that is used to protect a metal from oxidation. AL = 55%, Zinc = 43.5%, silicon = 1.5%.
Galvalume next generation. It is produced by alloying the aluminium, zinc, silicon and magnesium. 55% Al + 43.4% Zn & Mg + 1.6% Silicon.
A layer of magnesium and silicon is created on the surface of Galvalume alloy immersed in molten zinc. This manufacturing process enhances the strength, durability, workability and sustainability of steel. GLX has improved corrosion resistance by virtue of its characteristics self sealing ability by extra Mg-Zn layer stabilizes the self sacrificial reaction of Zinc.
GL (Alu-Zinc) – Aluminium, Zinc and Silicon Coating
GLX – Aluminium, Zinc, Magnesium and Silicon coating.
Steel sheets naturally trap heat. However Georoof sheets are equipped with superior cool roof technology paint resulting the decrease in overall temperature compered with other Roofings. Recommended to use insulators for better results.
Drumming sound is produced when rain falls on steel sheets. As georoof sheet have highest paint coating thickness and textured paint finish there is considerable reduction in this sound. Recommended to use insulators for better results.
Condensation, a natural phenomenon occurring during cold and rainy seasons, forms on surfaces like drinking glasses and car windows; to mitigate this in structures, adequate ventilation is recommended.
Cutting sheets with improper tools lead to uneven and exposed edges which are prone to corrosion. Therefore, it is highly recommended that only suitable and proper tools are used for cutting.
During drilling and screwing, tiny particles of the base material are generated on exposure to rain and dew, these particles cause staining. To prevent this, it is recommended that particular area be thoroughly cleaned post roofing.
Proper roof slope as the right angle is what makes the roof perfect. The angle of the roof slope should be from 35 to 45 degree. It will help avoid the possibility of clogs on the roof due to fallen leaves during monsoon.
Apply self-drilling fastness on the ribs of the roofing sheets and not in the valley where water flows. And it’s necessary to apply silicon sealant at all the screwed areas to avoid leakage.
Storage under wet conditions for long periods lead to bubbling of paint.
Corrosion of Zinc layer is called white rust.
Fungal growth is caused by the presence of water on the roof, which in turn is caused because of any obstruction to smooth flow of water. It may arise as a result of Factors like improper slopping and presence of leaves and other particles on the roof.
Black spot are caused due to excess lead prevent in the zinc coating. This is perfectly normal and it is not a defect.
Store away from materials that may damage the sheets. Stack the roofing sheets on wooden padding in a sloping position so that the water can drain away easily, if the number of sheets are less place them inclined to a wall. Cover the sheets with water resistant sheet and ensure sufficient air flow around them and during transportation arrange the sheets in a proper way with no moment and stack them with recommended number of sheets and load and unload with proper equipment.
During cutting it is highly recommended to use appropriate tools such as nibblers and scissors. The usage of marble cutters is highly discouraged as it can lead to the exposure of base metal and subsequent discoloration.
Appropriate tools for cutting
Ideal purlin Space
Right Angle
Overlap properly
Fit perfectly
Use proper screws on ribs
Use high quality accessories.
Clean the dust and remaining
Clean with water once.
Remove anything blocking the free flow of water periodically
Paint the cutting edges of the sheets
Make sure that proper ventilation required for to avoid condensation.
