It includes two 14-metre long lateral walls and one 9-metre long rear wall, in compliance with IAAF requirements.
It consists of twenty two 4-metre tall poles, built in two parts joined together by means of an internal upright, secured with a knob to facilitate assembly and disassembly operations. Each pole is joined to the next by means of metal bars, located in the lower part of the pole, which confer the necessary rigidity to the structure. A wooden stop barrier on the side facing the landing area prevents rolling shot puts from exiting the perimeter of the landing area. After a degreasing treatment, consisting of a pressured phosphate bath, the product is painted with polyester powder paint and polymerized at 200°C in an oven.
