It is made of reinforced concrete (mega strong and with lots of iron in it). More come soon……

Made only by professionals. It is ready-made reinforcement concrete (can be bought in many places in the DK, on ​​the internet) and it has arrived in a concrete truck. I have made quite a few of these stairs before and always dreamed of getting the right arch on it and I got a tip on it. Super easy and the result is super. It is important that you use reinforced concrete.!!! I will show you the next and the finished result soon. Finally I got the round shapes👍🏼💪🏼
