Engineered for extreme shear loads, quick installation, and long-term corrosion resistance in tropical industrial builds.
Hebei Sanbiao Fastener Manufacturing Co., Ltd. is a leading fastener manufacturing enterprise integrating production and sales. Over decades of intensive industrial development, our global reach has expanded, offering strategic supply chains that support critical infrastructure and civil developments in emerging markets like Gitarama, Rwanda.
We leverage premium materials including Q235B, 35# steel, 45# steel, 40Cr, 35CrmoA, and Q345B. Each structural component undergoes rigorous mechanical testing. From high-tensile steel structure bolts and torsion shear bolts to anchor bolts, our products are engineered to secure heavy machinery and large scale civil frames.
With streamlined transit routes serving Gitarama and the wider Southern Province of Rwanda, we minimize local lead times. We facilitate direct port-to-site shipping, customs clearing paperwork, and batch traceability certifications to ensure your operations never experience downtime.
Analyzing the local market realities and engineering standards required for Rwanda's second-tier logistics corridor.
Gitarama (Muhanga District), positioned strategically at the crossroads of the National Roads connecting Kigali with the Western and Southern Provinces, is rapidly converting into a major industrial and agricultural distribution hub for Rwanda. Under the Rwandan Government’s secondary city expansion framework, the region has seen substantial investments in modern warehousing, grain silos, agro-processing factories, and mid-rise commercial centers.
These structural developments demand heavy steel framing systems (PEB - Pre-Engineered Buildings) where self-drilling screws (drill screws) and high-strength fasteners play a mission-critical role. High-humidity levels in the central Rwandan highlands mean that standard carbon steel fasteners fail prematurely due to galvanic and atmospheric corrosion. Our specific focus is the distribution of advanced protective coatings, such as hot-dip galvanization and yellow zinc plating, which provide sacrificial protection to meet the 25+ year lifespan expectations of local developments.
Unlike traditional wood or sheet metal screws, self-drilling screws feature a tip designed like a drill bit (TEK point). They drill, tap, and fasten in a single rapid operation, eliminating pre-drilling. This drastically reduces labor costs and construction timelines for large-scale logistics warehouses in Rwanda.
Selecting the correct raw materials is paramount to preventing shear failure and structural collapse. Below is the technical specification roadmap for engineers designing frameworks in Gitarama:
| Steel Grade / Designation | Yield Strength (Min) | Tensile Strength | Primary Industrial Application |
|---|---|---|---|
| Q235B / Q345B | 235 - 345 MPa | 370 - 500 MPa | Standard light structural steel framing, purlins, and wall cladding sheets. |
| 45# Medium Carbon Steel | 355 MPa | 600 MPa | High durability studs, threaded rods, and standard grade 8.8 bolts. |
| 40Cr (Chromium Alloy) | 785 MPa | 980 MPa | Heavy-duty grade 10.9 structural bolts, high stress crane anchors. |
| 35CrmoA (Chrome-Moly) | 835 MPa | 1000+ MPa | Ultra-high-strength 12.9 tension-control bolts and wind turbine tower connections. |

A guide for engineering consultants and civil builders in Gitarama to choose the correct TEK points.
Selecting the wrong drill point can lead to burnt tips, broken fasteners, or insufficient pull-out resistance. The thickness of the steel framework dictates the required tip geometry:

Self-drilling screws (often called TEK screws) feature a point integrated with a miniature drill bit. They drill their own pilot hole, form threads, and complete the connection in a single continuous step. Self-tapping screws, on the other hand, require a pre-drilled pilot hole of a specific diameter before they can form threads inside the material.
For grade 10.9 and 12.9 fasteners, hydrogen embrittlement is a serious risk during acid cleaning or electroplating processes. We perform post-plating baking treatments within a controlled temporal window to release trapped atomic hydrogen from the steel microstructure, guaranteeing high ductility and fatigue resistance under static and dynamic loading.
Hot-Dip Galvanizing (HDG) or heavy Yellow Zinc coatings are strongly recommended. They provide a thicker barrier of protective zinc layer, which sacrificially corrodes to protect the structural steel underneath. For high-humidity structures and agricultural processing facilities, standard zinc electroplating may only provide short-term protection.
Our fasteners are manufactured and tested in strict accordance with ISO 9001:2015, CE, and SGS international standards. Upon shipment, clients receive material test reports (MTRs) detailing raw chemical composition (such as carbon, chromium, and molybdenum levels), mechanical properties, tension test data, and hardness profiles.
Yes. Our integrated production facilities utilize advanced multi-station cold-heading machines and CNC tooling lines. We can manufacture customized U-bolts, foundation anchor layouts, embedded plates, and custom dimensions to align with your engineered blueprints. Send your CAD drawings to our design office for pricing.
We offer flexible shipping terms including FOB, CIF, and CFR. Shipments are safely packed in standard export cartons on reinforced pallets to withstand ocean and overland transit. Our logistics department coordinates closely with regional carriers operating along the East African transport corridors directly to Kigali and Gitarama.
