Insights into local structural requirements, severe climate resilience, and modern prefabricated construction developments.
Russian civil construction has seen a rapid shift toward Light Gauge Steel Framing (LSTK) systems for logistical complexes, retail centers, and agricultural buildings. This trend drives significant demand for self-drilling screws capable of penetrating structural steel up to 12.5mm without pre-drilling, while maintaining structural integrity.
Siberian and Far-Eastern industrial projects operate under extreme temperatures down to -50°C. Standard fasteners can suffer head shear failures due to low-temperature embrittlement. Sinsun's optimized carbon steel formulation ensures the necessary ductility and fatigue life to withstand thermal movement and wind loads.
From the industrial zones of the Urals to the coastal dampness of Saint Petersburg, structures require robust defense against corrosion. We provide advanced multi-layer coatings, including Ruspert and zinc diffusion coatings, to ensure over 1,000 hours of salt spray resistance (ISO 9227) without performance loss.
Sinsun's self-drilling screws are manufactured using premium C1022A raw steel sourced from Ansteel Group, designed for high-performance drilling. Our production processes feature critical metallurgical and mechanical controls:
| Coating Type | Layer Thickness (μm) | Salt Spray Resistance (ISO 9227) | Corrosion Category (ISO 12944) | Best Used For |
|---|---|---|---|---|
| Electro-Zinc Plating (Blue/White) | 5 - 8 μm | 72 - 120 Hours | C1 - C2 (Dry Indoor Environments) | Internal steel framing, drywall installation, indoor apparatus assembly. |
| Yellow Zinc Plated | 8 - 12 μm | 96 - 150 Hours | C2 (Dry & Lightly Polluted Zones) | Wood construction framing, general interior steel joinery. |
| Dacromet Coating | 15 - 25 μm | 500 - 1000 Hours | C3 - C4 (Industrial & Moderately Humid) | Automotive structural mounting, agricultural metal building frames. |
| Ruspert Coating (Silver/Grey) | 20 - 30 μm | 1000 - 1500 Hours | C4 - C5 (Heavy Industrial & Marine) | Outer sandwich panel cladding, roofs, coastal industrial warehouses. |
| Hot-Dip Galvanized (HDG) | 45 - 65 μm | 1500+ Hours | C5 (Highly Aggressive Environments) | Heavy structural steel bridges, high-corrosion offshore installations. |

Our self-drilling screws comply with major Russian norms, including GOST ISO 15480 (self-drilling screws with tapping screw threads) and GOST R 56782. Every batch is manufactured to meet these specific dimensional and mechanical properties.
Our standard #3 drill-point screws can pierce up to 6mm steel plates. For heavier structural connections, our #5 drill-point screws can drill and tap through up to 12.5mm of structural steel (St3Sp / GOST 380) in a single step without pre-drilling.
We use fully kilned, fine-grained C1022A carbon steel with controlled spheroidizing annealing. By keeping phosphorus and sulfur levels low, we minimize cold shortness. Our heat treatment processes prevent hydrogen embrittlement, ensuring safety at temperatures down to -50°C.
We offer comprehensive OEM/ODM packaging services, including custom box printing, Russian-language labeling (including barcode registrations), and small plastic pack options. Our 12,000 sqm warehouse features high-speed packaging lines to support large-scale orders.
Yes, we provide pre-production samples for physical and mechanical laboratory verification. Once your engineers approve the sample dimensions and drilling speed, we initiate mass production under identical tolerances.
We support FOB, CFR, CIF, and DDP terms. Goods can be dispatched via rail container routes passing through Manchuria/Zabaikalsk directly to your warehouse, or by sea container shipments to Vladivostok, Saint Petersburg, or Novorossiysk ports.
Every production run receives a unique tracking number linked to the chemical analysis certificate of the raw wire rod. We store reference samples from each batch for 3 years, allowing for swift quality audits if needed.
Our comprehensive range of industrial anchors, nails, bolts, and specialized connection components designed for diverse building and infrastructure applications.
