It is the strip along the edge of the tarpaulin fabric that slides into the groove of an aluminum profile and keeps the entire structure properly tensioned. Without it, the tarpaulin sags, wrinkles, and wears out quickly. With it, the structure can last for years.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In this guide, we explain what keder is, what types exist, what materials it is made from, how to choose the correct size, and where it is used. This material will be useful both for beginners making their first tarpaulin and for manufacturers looking for a reliable supplier.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Is Keder (Luff Tape)<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Keder is a flexible tape made of a PVC cord wrapped in polyester fabric with PVC coating. It is sewn or welded (using HF welding) along the edge of a tarpaulin fabric and then inserted into the groove of an aluminum or steel profile. The keder fixes the tarpaulin to the frame without additional fasteners, hooks, or holes.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In different industries and regions, this product may also be called <strong>keder<\/strong>, <strong>luff tape<\/strong>, or <strong>keder tape<\/strong>. These names refer to the same product \u2014 only the terminology differs depending on the country or professional environment.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How Keder Works: Fastening Principle<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The principle is simple but extremely effective. The keder is welded or sewn along the edge of the tarpaulin fabric, becoming an integral part of the cover. This edge is then inserted into the groove of an aluminum profile mounted on the frame structure.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The cord inside the keder is thicker than the groove opening, preventing it from slipping out. The tape flaps (single or double) distribute tension evenly along the entire length and prevent the fabric from shifting. As a result, the tarpaulin remains evenly tensioned without wrinkles or sagging, while still being easy to remove by simply sliding the keder out of the groove.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Types of Keder: Single and Double<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The main classification of keder is based on the number of flaps.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Single keder (single-flap)<\/strong> \u2014 has one side flap. Suitable for lightweight tarpaulin structures with low loads: small canopies, seasonal shelters, and decorative tarpaulin curtains.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Double keder (double-flap)<\/strong> \u2014 has two symmetrical flaps on both sides of the cord. This is the standard solution for industrial and commercial tarpaulins. Two flaps distribute tension more evenly, hold the fabric more securely, and withstand repeated installation and removal better.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For most applications \u2014 truck tarpaulins, tents, awnings, industrial canopies \u2014 <a href=\"https:\/\/tehnotent-plus.com\/en\/product\/double-keder-7-5mm-white-pvc-luff-tape\/\" type=\"link\" id=\"https:\/\/tehnotent-plus.com\/product\/keder-podviynyy-7-5-mm-bilyy-pvkh-tasma-kedrova-dlia-tentu-liktros\/\">double keder<\/a> is recommended. It is more reliable and durable.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"555\" src=\"https:\/\/tehnotent-plus.com\/wp-content\/uploads\/2026\/05\/keder-podvijnyi-vs-odynarnyi-koliazh-1024x555.jpg\" alt=\"Double and single PVC keder \u2014 comparison of keder tape types for tarpaulins\" class=\"wp-image-11965\" srcset=\"https:\/\/tehnotent-plus.com\/wp-content\/uploads\/2026\/05\/keder-podvijnyi-vs-odynarnyi-koliazh-1024x555.jpg 1024w, https:\/\/tehnotent-plus.com\/wp-content\/uploads\/2026\/05\/keder-podvijnyi-vs-odynarnyi-koliazh-300x163.jpg 300w, https:\/\/tehnotent-plus.com\/wp-content\/uploads\/2026\/05\/keder-podvijnyi-vs-odynarnyi-koliazh-768x416.jpg 768w, https:\/\/tehnotent-plus.com\/wp-content\/uploads\/2026\/05\/keder-podvijnyi-vs-odynarnyi-koliazh-600x325.jpg 600w, https:\/\/tehnotent-plus.com\/wp-content\/uploads\/2026\/05\/keder-podvijnyi-vs-odynarnyi-koliazh-220x119.jpg 220w, https:\/\/tehnotent-plus.com\/wp-content\/uploads\/2026\/05\/keder-podvijnyi-vs-odynarnyi-koliazh.jpg 1200w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n<\/div>\n\n\n<h2 class=\"wp-block-heading\">What High-Quality PVC Keder Is Made Of<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Keder consists of two main components: the <strong>cord<\/strong> and the <strong>outer layer<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>The cord<\/strong> is the core that determines the diameter and rigidity. High-quality cords are made from frost-resistant PVC. They remain flexible at temperatures down to \u201330\u00b0C and do not crack in freezing conditions.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>The outer layer<\/strong> is polyester fabric with PVC impregnation or coating. It protects the cord from mechanical damage, ensures proper bonding with the tarpaulin fabric during welding or sewing, and affects how smoothly the keder slides inside the profile groove.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">What to pay attention to when choosing:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Thread density<\/strong> \u2014 1100 dtex and higher means increased tear resistance. Lower density is suitable for lightweight structures.<\/li>\n\n<li><strong>Coating weight<\/strong> \u2014 460 g\/m\u00b2 is considered a good indicator for outdoor use. Materials with this coating resist UV exposure and moisture.<\/li>\n\n<li><strong>Color<\/strong> \u2014 the most common options are white and black. White looks cleaner on light-colored tarpaulins, while black suits darker and technical structures.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">How to Choose the Right Size: 7.5 mm or 10 mm<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The size of keder is determined by the cord diameter and must exactly match the width of your aluminum profile groove.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong><a href=\"https:\/\/tehnotent-plus.com\/en\/product\/double-keder-7-5mm-white-pvc-luff-tape\/\" type=\"link\">Double Keder 7.5 mm White PVC<\/a><\/strong> is the most common standard. It fits most aluminum profiles used in trade tents, awnings, tarpaulin curtains, and lightweight industrial structures.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong><a href=\"https:\/\/tehnotent-plus.com\/en\/product\/double-keder-10mm-white-pvc-luff-tape\/\">Double Keder 10 mm White PVC<\/a><\/strong> is designed for profiles with wider grooves. It is typically used in large structures: tents from 6\u00d76 m, industrial pavilions, and tarpaulins for heavy-duty trailers and semi-trailers.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Before ordering, <strong>measure the groove of your profile<\/strong>. If the keder is too thin, it will not hold securely. If it is too thick, it simply will not fit into the groove. The ideal fit should require slight effort but without deformation.<\/p>\n\n\n<div class=\"wp-block-image is-style-default\">\n<figure class=\"aligncenter size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"683\" src=\"https:\/\/tehnotent-plus.com\/wp-content\/uploads\/2026\/05\/keder-pvh-v-pazu-aluminievogo-profiliu-1024x683.jpg\" alt=\"PVC keder tape in roll \u2014 double luff tape for manufacturing and repair of tarpaulins\" class=\"wp-image-11964\" srcset=\"https:\/\/tehnotent-plus.com\/wp-content\/uploads\/2026\/05\/keder-pvh-v-pazu-aluminievogo-profiliu-1024x683.jpg 1024w, https:\/\/tehnotent-plus.com\/wp-content\/uploads\/2026\/05\/keder-pvh-v-pazu-aluminievogo-profiliu-300x200.jpg 300w, https:\/\/tehnotent-plus.com\/wp-content\/uploads\/2026\/05\/keder-pvh-v-pazu-aluminievogo-profiliu-768x512.jpg 768w, https:\/\/tehnotent-plus.com\/wp-content\/uploads\/2026\/05\/keder-pvh-v-pazu-aluminievogo-profiliu-600x400.jpg 600w, https:\/\/tehnotent-plus.com\/wp-content\/uploads\/2026\/05\/keder-pvh-v-pazu-aluminievogo-profiliu-220x147.jpg 220w, https:\/\/tehnotent-plus.com\/wp-content\/uploads\/2026\/05\/keder-pvh-v-pazu-aluminievogo-profiliu.jpg 1536w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n<\/div>\n\n\n<h2 class=\"wp-block-heading\">Where PVC Keder Is Used<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The application range of keder is much wider than it may seem at first glance.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Transport and logistics.<\/strong> Tarpaulins for trucks, trailers, and semi-trailers are one of the largest application areas. Here, keder works under constant loads, vibration, and temperature changes.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Trade and events.<\/strong> Tents, trade booths, and exhibition pavilions \u2014 everywhere fast assembly and dismantling are required. Keder allows tarpaulins to be installed or removed within minutes without tools.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Awnings and canopies.<\/strong> <a href=\"https:\/\/tehnotent-plus.com\/en\/product-category\/retractable-awning\/\" type=\"link\">Retractable terrace awnings<\/a>, balcony canopies, and entrance covers \u2014 here keder secures the fabric inside the guide rail and ensures even tension during extension.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Tarpaulin curtains.<\/strong> PVC curtains for warehouses, production facilities, cold rooms, and restaurant terraces are also fixed using keder in the upper profile.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Greenhouses and agriculture.<\/strong> Tarpaulin shelters for agricultural structures, protective covers for machinery, and grain storage facilities.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How Keder Is Attached to Tarpaulin Fabric<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">There are two main methods.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>HF welding (high-frequency welding)<\/strong> is the most reliable and widely used industrial method. The keder is literally welded to the PVC fabric at the molecular level, creating a joint stronger than the material itself. This is the method we use at Techno Tent Plus production.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Sewing<\/strong> is suitable for fabric-based materials or where HF welding equipment is unavailable. The seam should be made with strong polyester threads and double stitching.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Common Mistakes When Choosing and Installing Keder<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The most common mistake is <strong>choosing the wrong size<\/strong>. A 7.5 mm keder inside a 10 mm profile simply will not hold securely. Always check the groove size before ordering.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The second mistake is <strong>cheap keder without UV protection<\/strong>. Such material turns yellow and becomes brittle after just one season outdoors. Always pay attention to coating specifications.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The third mistake is <strong>an excessively tight fit inside the groove<\/strong>. If the keder enters with too much force, it may damage the fabric during installation or make winter removal difficult.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Where to Buy PVC Keder in Ukraine<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Techno Tent Plus<\/strong> manufactures tarpaulins, awnings, canopies, and PVC products \u2014 and uses keder in its own production every day.
