Constructed from high-tensile cold-reduced mild steel meeting EN10219 standards, our 50mm x 50mm square box sections deliver exceptional strength in a hollow structural section (HSS) profile. These square steel tubing sections come with a mill finish and are stocked in lengths up to 4m.

While the raw mill finish means some minor surface imperfections, these square box sections offer outstanding load-bearing capabilities combined with lightweight rigidity. They are perfect for construction projects, manufacturing applications, and heavy-duty DIY work requiring durable square steel tubing.

so pleased with how our hallway is coming along 🥰 here is a little run down of what we’ve done 🎨 we painted the walls, skirting & door frames in slipper satin (paint matched at b&q) - I think I also want to do the ceilings as they need a refresh anyway 🪚 we panelled the wall longest wall which I loved doing, the most difficult part was going around the plug sockets - I ordered from cutmy.uk which was made to measure & absolutely brilliant 🎨 the panelling is painted in elephant’s breath (also paint matched at b&q) 🪞& then we added the mirrors 💡changed the light fitting 🖤 painted the little cabinet in pitch black - a bit risky but so pleased with how it came out 🪑added a bench and cushions 🌿 we bought a new (big) plant baby, bird of paradise & a large pot for the corner 🧥and some gorgey coat hooks for under the stairs made by ardovie_wood who we found on etsyuk We’re going to look for some baskets to go under the bench for shoes, and I want to get a new lamp too! And the current plan is the change the carpet to hard flooring next year. ➡️ swipe to the end to see the before photo • #Hallway #HallwayDecor #HallwayInspo #HouseUpdates #HomeDecor #HomeInterior #Panelling #GivingItAGo

We are struggling with the master bedroom. We now have some lights and a bit of colour. We need some excitement! Any suggestions? Really easy to panel with cutmy.uk and we love our new dusk.com bed. #laytondwh #dwhlayton #layton #cutmy

We received this beautiful photo from Robert on Trust Pilot of his charcoal slat panelling that he has used for his bar island. We love that we are seeing more and more of our panelling being used on furniture!

LIFE LATELY 🌲✨ I realised I legit NEVER post stills anymore, and shiney reels don't always show reality. So next year I vouch to make a bigger effort to post more pictures that capture the good bad & ugly! 1. The finished stairs garland after 599 attempts at tying a bow we got there - if you saw my stories you'll know this is an achievement 🤣 2. A moment of still/ gratitude with my babies 3. 4 month milestone!! Feels like 4 minutes and 4 years all in one. 4. A small win to be celebrated - I was in overwhelm city and I forced myself out the house. Obvs felt a million times better for it so need to remember for next time! 5. My breakfast bar of dreams 🥰 so happy with how's it's turned out - just need to make my mind up on paint. 6. Nap trapped and savouring the moment. She won't be this little again and as tough as it is I would swap anything to keep these cuddles longer 🥹 Bit different from me today!! Happy Friday Homeys 🥰 CHS x
