T Racking Just won a big tender for one complete project of steel warehouse structure and pallet racking in Africa.
The customer is a Furtune 500 shipping company, they want to build up a warehouse for cold food storage in Somali. Customer get the name of T Racking from Intelnet.
After several weeks email communication, customer ask us to offer a complete quotation and date sheet for the total warehouse.
T Racking not only make pallet racking system, but also other warehouse part like steel structure, cold store equipment, etc.
Attached part of calculatoin sheet for the project.
