I would use 40mmx40mmx5mm angle for side rails of ramps .what are you using inbetween rails

smaller angle between the rails

25mmx25mmx3mm will be fine inbetween

brilliant thank you
you sound like you have done this before
again thank you

40 x 40 on mine with heavy duty mesh in between. 1.5m x 250mm If I was making them again I would make them wider to suit the different tracks on the car.

Don't use "bedstead angle" altough it has a higher tensile strength it has a higher carbon content which results in brittle welds unless heat treated.
