The patented Umbrella folding roof
with clamped stiffening ring
The SOYK-COVER® is an innovative solution and further development of the Alu Dome already known and used on the market, which revolutionizes environmental protection in large industrial tank farms and chemical parks and at the same time enables efficient storage. Our developed and patented umbrella folding roof with clamped stiffening rings contributes actively to our sustainable business model. It provides support especially in classic environmental fields as sewage management and emission protection.






Innovative umbrella folding roof for flat-bottom tanks.
Thanks to SOYK-COVER®, rainwater is safely drained off and does not get into direct contact with the storage medium. This remains free of contamination and costly wastewater treatment is avoided. At the same time, SOYK-COVER® contributes to air pollution control by reducing emissions, thus meeting the increasingly stringent requirements of the German Clean Air Act (TA Luft).
With SOYK-COVER®, we offer an innovative solution that advances environmental protection while enabling efficient and sustainable storage. Trust our expertise and rely upon an environmentally friendly solution for your tank facilities.
Advantages of the SOYK-COVER®
Suspended and clamped
stiffening rings against buckling
By using a clamped mounting bracket on the tank, any number of stiffening rings can be mounted on the tank. This extends the endurance and prevents buckling. The mounting is done while the tank is in operation, no welding & hot works must be done.
