For European steel construction projects, structural fasteners are not treated like ordinary hardware. If a bolt assembly is used in a regulated structural application, buyers must check whether CE marking, Declaration of Performance, and the correct EN standard apply.<\/p>\n\n\n\n
This is where many importers make mistakes.<\/p>\n\n\n\n
They ask for \u201c8.8 structural bolts\u201d or \u201cDIN bolts for steel structure,\u201d but the European project may require CE-marked assemblies under EN 15048 or EN 14399. A standard bolt may look similar, but if the marking, documentation, and assembly control are missing, it may not be accepted on site.<\/p>\n\n\n\n
CE marking for construction products shows that the manufacturer has declared product performance according to the relevant European rules. It is not simply a quality logo. It is linked to the applicable harmonized standard, factory production control, testing, traceability, and required documents.<\/p>\n\n\n\n
For structural bolting, buyers should confirm whether the project requires:<\/p>\n\n\n\n
Buyers comparing structural fastener options can review available \u9ad8\u5f3a\u5ea6\u7d27\u56fa\u4ef6<\/a> \u548c \u6807\u51c6\u7d27\u56fa\u4ef6<\/a> \u5728\u51c6\u5907\u8be2\u4ef7\u4e4b\u524d\u3002<\/p>\n\n\n\n European structural fasteners are commonly divided by whether the connection is non-preloaded or preloaded.<\/p>\n\n\n\n The key word is \u201cassembly.\u201d Structural fasteners for CE-marked supply are often controlled as bolt, nut, and washer assemblies. Buying bolts from one source, nuts from another, and washers from a third may create compliance and traceability problems.<\/p>\n\n\n\n Ask the supplier which standard the fasteners follow. Do not accept only \u201cstructural bolt\u201d as a complete description.<\/p>\n\n\n\n RFQ\u5e94\u6ce8\u660e\uff1a<\/p>\n\n\n\n For full project lists, buyers can also review the broader \u7d27\u56fa\u4ef6\u4ea7\u54c1<\/a> \u8303\u56f4\u3002<\/p>\n\n\n\n Structural fastener packaging should allow the buyer, contractor, and inspector to identify the goods clearly.<\/p>\n\n\n\n Labels should include:<\/p>\n\n\n\n Poor labeling can delay receiving, inspection, and project approval.<\/p>\n\n\n\n European structural fasteners may be supplied with different finishes depending on the project environment. Common options include plain, zinc plated, hot-dip galvanized, zinc flake, or other specified coatings.<\/p>\n\n\n\n For outdoor steel structures, corrosion protection must be confirmed carefully. Hot-dip galvanizing can improve protection, but coating thickness may affect thread fit. Zinc flake coatings may be preferred in some high-strength assemblies where controlled thickness and corrosion resistance matter.<\/p>\n\n\n\nEN 15048 \u4e0eEN 14399<\/h2>\n\n\n\n
