The 10&#215;10 cm tube is used in larger structures or those with heavier loads: garages, large porches, roofs, and home extensions.

Screws included. <\/li>\n<li>It features flanges: side plates through which the joint is screwed to the tube, also allowing panels, enclosures, or other profiles to be attached.<\/li>\n<\/ul>\n<h2>Assembly<\/h2>\n<p>Fit the tubes into the piece, check the corner bracket, and screw it in place. No welding or special machinery is needed, so the structure can be assembled directly on site. For this connector you will need <a href=\"https:\/\/starmodul.com\/en\/galvanized-steel-pipe-10x10-cm-2mm-thick-price-per-ml\/\">2 mm 10&#215;10 cm galvanized steel tube<\/a> or <a href=\"https:\/\/starmodul.com\/en\/galvanized-steel-pipe-10x10-cm-3mm-thick-price-per-ml\/\">3 mm 10&#215;10 cm tube<\/a>; we can ship it cut to size.  <\/p>\n<p>See also: <a href=\"https:\/\/starmodul.com\/en\/unions-tube-10x10-cm-with-fins\/\">all 10&#215;10 cm tube joints with flanges<\/a> and the <a href=\"https:\/\/starmodul.com\/en\/3d-configurator-metal-structure\/\">3D structure configurator<\/a>, which calculates the joints and tubes for your project.<\/p>\n<h2>Frequently asked questions<\/h2>\n<h3>Does the 1010-21 include screws?<\/h3>\n<p>Yes. Each connector is supplied with its screws. <\/p>\n<h3>Is welding required?<\/h3>\n<p>No. The entire StarModul system is screwed together, so it can be assembled and disassembled without welding. <\/p>\n<h3>How long does shipping take?<\/h3>\n<p>With stock, 2\u20133 days in Catalonia and Aragon and 7\u20138 days in the rest of Spain. Without stock, 2\u20133 weeks. <\/p>\n<h3>Can you prepare the complete structure?<\/h3>\n<p>Yes. We work to measure and can send you the complete kit: connectors, cut tubes, panels for facade and roof, flashing, and screws. <a href=\"https:\/\/starmodul.com\/en\/contact\/\">Request a quote<\/a>. <\/p>\n<\/details>\n","protected":false},"excerpt":{"rendered":"[3d_viewer id=\"4326\"]\n","protected":false},"featured_media":6505,"template":"","meta":[],"product_brand":[],"product_cat":[113,121,126],"product_tag":[],"class_list":["post-9879","product","type-product","status-publish","has-post-thumbnail","product_cat-bolted-joints-for-steel-structures","product_cat-finned-bolted-joints","product_cat-unions-tube-10x10-cm-with-fins","first","instock","taxable","shipping-taxable","purchasable","product-type-simple"],"_links":{"self":[{"href":"https:\/\/starmodul.com\/en\/wp-json\/wp\/v2\/product\/9879","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/starmodul.com\/en\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/starmodul.com\/en\/wp-json\/wp\/v2\/types\/product"}],"version-history":[{"count":6,"href":"https:\/\/starmodul.com\/en\/wp-json\/wp\/v2\/product\/9879\/revisions"}],"predecessor-version":[{"id":35543,"href":"https:\/\/starmodul.com\/en\/wp-json\/wp\/v2\/product\/9879\/revisions\/35543"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/starmodul.com\/en\/wp-json\/wp\/v2\/media\/6505"}],"wp:attachment":[{"href":"https:\/\/starmodul.com\/en\/wp-json\/wp\/v2\/media?parent=9879"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/starmodul.com\/en\/wp-json\/wp\/v2\/product_brand?post=9879"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/starmodul.com\/en\/wp-json\/wp\/v2\/product_cat?post=9879"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/starmodul.com\/en\/wp-json\/wp\/v2\/product_tag?post=9879"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
