You assemble the four corner pieces, matching side panels, and horizontal cross-braces from the inside. From the outside, you won't see a single screw—just a clean, tranquil steel surface that will develop its signature weathered patina over time.\u003c\/p\u003e\n\u003cp\u003eThis kit really shines where pre-welded beds reach their limits: for long beds placed along fences or house walls, and for gardens that are only accessible through narrow gates, stairs, or through the house.

The number of parts and their individual widths are determined by your dimensions. The horizontal cross-braces reinforce the walls against soil pressure. They are positioned below half the bed's height, leaving plenty of room in the upper area for digging and planting.\u003c\/p\u003e\n\u003cp\u003eFor assembly, you will need an Allen key and a wrench for M6 screws. Start with one corner piece and attach the side panels one by one. A tip from our workshop: At first, only loosely tighten the screws in the middle of the three holes. This leaves room for adjustment; tighten all screws completely only once all parts and braces are in place. Assembly instructions are included.\u003c\/p\u003e\n\u003cp\u003eThe top edge is double-folded, and the corners are welded at the top. The minimum dimension increases with the sheet thickness: 2 mm sheet metal receives at least 30 × 20 mm, 3 mm gets 40 × 25 mm, 4 mm gets 45 × 35 mm, and 5 mm gets 60 × 40 mm (width × height). You can set a wider support edge of up to 100 mm in the configurator at no extra cost. The folded edge faces inward or, if you want a supporting rim to lean on, outward. At the bottom, a simple 30 mm fold stabilizes the stand. The kit does not have a floor and remains in open contact with the ground.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDon't want to assemble it yourself?\u003c\/strong\u003e Up to a length of 240 cm, the bed is also available as a \u003ca href=\"https:\/\/kirchberger-metall.de\/products\/hochbeet-cortenstahl-nach-mass-verschweisst\" title=\"Custom-made welded Corten steel raised bed\"\u003efully welded custom raised bed\u003c\/a\u003e, optionally with a welded-in base.

You can speed up the process by degreasing the parts with brake cleaner or white spirit before or immediately after assembly: Rust will form sooner on a grease-free surface. Leave about 1 cm of air around the bed near walls or neighboring beds. On light-colored stone slabs, rust may initially run off and leave stains; it is better to place a mat or a gravel bed underneath.\u003c\/p\u003e\n\u003ch3\u003eGenuine Corten steel – not \"structural steel with a rust look\"\u003c\/h3\u003e\n\u003cul\u003e\n\n\u003cli\u003eWeather-resistant alloyed with copper and chromium – not untreated structural steel St37 or S235.\u003c\/li\u003e\n\n\u003cli\u003eForms a firmly adhering protective patina instead of porous, flaking rust.\u003c\/li\u003e\n\n\u003cli\u003eNo rusting through: decades of service life, virtually maintenance-free.\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n\u003cp\u003eWhy this is a technical rather than just a visual difference is explained in our guide \u003ca href=\"https:\/\/kirchberger-metall.de\/blogs\/metallbau-fachwissen-tipps\/cortenstahl-vs-baustahl-st37-unterschied\" target=\"_blank\" rel=\"noopener\"\u003eCorten steel vs. structural steel St37\u003c\/a\u003e.\u003c\/p\u003e","brand":"Kirchberger Metall","offers":[{"title":"Default Title","offer_id":58909984620808,"sku":"HB-COR-BS","price":383.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/3164\/2888\/files\/hochbeet-cortenstahl-bausatz-innenansicht-querstreben.png?v=1790622124","url":"https:\/\/kirchberger-metall.de\/en\/products\/hochbeet-cortenstahl-bausatz-nach-mass","provider":"Kirchberger Metall - Metallbau Onlineshop","version":"1.0","type":"link"}
