Drop-Shipping & Freighting

With relationships with a number of suppliers for overnight, domestic and international freight we can coordinate delivering product direct to your end customer or manufacture and hold stock in bulk for efficient freighting to you.

GYRO was approached by Energy Distribution Business, PowerNet, to design a retrofittable Pillar cover for older concrete plinths that were in use for Low Voltage distribution across their Network. 

"The new pillar box cover has worked for us by replacing the existing metal lid and reducing potential safety hazards. If an electrical fault occurs inside the box, the plastic lid doesn’t become live - which is a very important factor in our line of work for the safety of the general public and our PowerNet team.
We really enjoyed working with GYRO Plastics, they were fantastic to deal with, and also very efficient. Throughout the project, we worked with GYRO Plastics Designer Malcolm  Brown  who took our brief and came up with a design that works well for our business. GYRO Plastics provided great customer services and we look forward to working with them on our next project.”
