Materials Management Department

Temporary equipment is backbone of construction. Therefore, the quality of equipment matters in every construction project. Sansin Sangyo thrives to give quality service with quality goods as part of our day to day rental service.

For this reason, we have adopted the catchphrase ‘Visualization of Peace of Mind’ and have been providing quality and safer materials through cleaning, repairing and refurbishing the materials before renting it to our customers.


The returned scaffolding and equipment is checked and then separated for cleaning, repair and maintenance. Our train staff makes sure that all the equipment is well-maintained and is in the best condition for our customers.


All maintenance is carried out in accordance to our strict maintenance standards. All equipment is inspected and stored to ensure the best condition for delivery. To increase efficiency or professional staff uses automatic Keren Machines (heavy cleaning devices). With this process we are able to meet the demands of our customers and maintain our strict quality standards.


All damaged equipment will be repaired by our professional staff. Before the equipment can be delivered to a customer it must pass our rigorous safety and quality standards.


All equipment is cleaned with high pressure washers to remove paint, dirt, concrete and other materials. After the equipment is cleaned it has to pass our rigorous safety and quality control standards before they are reused.
