Engineered to meet the rigorous demands of Vietnam's tropical climate and heavy infrastructure projects.
Vietnam has rapidly emerged as one of the most dynamic economies in Southeast Asia. With a massive influx of Foreign Direct Investment (FDI) from global tech giants and manufacturing powerhouses, the country is undergoing unprecedented industrialization. This rapid growth has triggered an immense demand for high-quality building materials, specifically wholesale structural bolts and heavy-duty fasteners.
Major infrastructure projects are reshaping the nation. From the ambitious North-South Expressway project and the construction of the Long Thanh International Airport near Ho Chi Minh City, to the expansion of deep-sea ports in Hai Phong and Ba Ria-Vung Tau, structural integrity is paramount. These mega-projects require thousands of tons of reliable, certified structural bolts such as ASTM A325, A490, DIN 6914, and EN 14399. As a leading supplier and factory, we are uniquely positioned to serve the Vietnamese market by providing bulk, high-strength fasteners that meet both international and local construction standards (TCVN).
Furthermore, the geographic proximity between China and Vietnam, bolstered by trade agreements like RCEP, allows for highly efficient logistics, fast delivery times, and cost-effective wholesale pricing. This strategic advantage makes our factory the preferred partner for Vietnamese contractors, steel structure fabricators, and hardware distributors.
Ningbo Zhongli Bolts Manufacturing Co., Ltd. founded in 2003, is a professional manufacturer of high-strength fasteners in different specifications for various models, which is covering an area of about 10,000 square meters, registered capital of 1500,000 RMB, with the total annual productivity of 8,000 tons per year.
Our main products ZYL brand fasteners include structural hex bolts ASTM A325 type 1, A490, hex head bolts DIN931, DIN933, EN14399, DIN6914, ISO4014, ISO4017 Gr8.8 Gr10.9 Gr12.9, ANSI B18.2.1 UNC and UNF Gr5, Gr8, fine pitch hex bolts DIN960, DIN961, hex socket cap screws DIN912, ISO4762 with surface Black, Zinc plated, Hot dip galvanized. Diameters from M10 to M48, length no limited.
Through scientific management, we obtained the ISO9001 certificate of Quality Management System. Quality is the most important for us. We have strict production and inspection equipments to support this point. We are actively expanding our footprint in Southeast Asia, particularly focusing on serving the robust Vietnam market.
Read More About Us
Vietnam is a regional hub for Pre-Engineered Building fabrication. Industrial zones in Bac Ninh, Binh Duong, and Dong Nai are filled with massive factories built for multinational corporations. Our high-tensile hex bolts (Grade 8.8, 10.9) and structural nuts are essential for assembling these steel frameworks quickly, safely, and cost-effectively.
Under Vietnam's Power Development Plan VIII (PDP8), the country is aggressively expanding its renewable energy sector, particularly offshore wind farms along the coastlines of Binh Thuan and Ninh Thuan. These turbines face extreme wind loads and corrosive saltwater environments. We supply specialized Hot-Dip Galvanized (HDG) and Dacromet-coated stud bolts and heavy hex bolts designed to withstand these harsh marine conditions.
With the continuous expansion of metro lines in Hanoi and Ho Chi Minh City, as well as cross-river bridges in the Mekong Delta, the demand for fatigue-resistant structural fasteners is critical. Our products undergo rigorous tensile and hardness testing to ensure they meet the safety standards required for dynamic load-bearing infrastructure in Vietnam.
Advanced manufacturing technology ensuring high precision and durability for every bolt.
The fastener market in Vietnam is undergoing a significant quality transition. In the past, lower-grade commercial bolts were sufficient for general construction. However, with the influx of international engineering firms and stricter building codes, the demand has sharply shifted towards high-tensile structural bolts (Grade 8.8, 10.9, and 12.9). Contractors in Vietnam are now prioritizing safety, traceability, and certified performance over mere low costs.
Another major trend is the focus on advanced anti-corrosion surface treatments. Vietnam's long coastline and tropical monsoon climate create highly corrosive environments. Standard zinc plating is often insufficient for outdoor structures. As a result, we are seeing a massive surge in orders from Vietnamese clients for fasteners with Hot-Dip Galvanization (HDG), Zinc-Nickel alloy plating, and Geomet/Dacromet coatings. Our factory is fully equipped to provide these advanced surface treatments, ensuring a lifespan of decades for steel structures built in Vietnam.
Finally, supply chain resilience has become a priority. Vietnamese distributors prefer suppliers who can maintain large inventories and offer rapid customization. Our facility, with an annual productivity of 8,000 tons and direct shipping routes to Hai Phong and Cat Lai ports, ensures that your project timelines are never delayed due to fastener shortages.
