Premium structural profiles engineered to withstand harsh Middle Eastern desert climates and highly corrosive coastal environments.
Egypt is undergoing a historic urban and economic transformation. Driven by the Egypt Vision 2030 national agenda, the demand for high-strength structural materials has escalated dramatically. Mega-development projects, including the New Administrative Capital (NAC), the Suez Canal Economic Zone (SCZONE) development, and massive reclamation projects in Toshka and the West Delta, require steel materials that offer robust mechanical strength and superior longevity.
However, Egypt’s unique geographic and climatic parameters present severe environmental challenges for metal infrastructure. From the high coastal humidity and salinity of Alexandria and Damietta to the scorching desert heat and dust storm abrasion in the New Valley Governorate, standard carbon steel structures degrade quickly without appropriate protective coatings. This environmental reality makes Hot Dip Galvanized (HDG) square and rectangular steel tubes the preferred structural element for local civil engineers and industrial planners.
By submerging cleaned carbon steel tubes into molten zinc at temperatures of approximately 450°C, a metallurgical bond is formed, creating several layers of zinc-iron alloy. This barrier stands up to sand erosion and blocks moisture, oxygen, and corrosive salts, ensuring maintenance-free performance for up to 50 years.
How Hot Dip Galvanized Hollow Sections are applied across Egypt’s major industrial sectors.
In major reclamation zones like Toshka, East Oweinat, and the West Delta, our pre-galvanized and hot-dip galvanized square tubes form the framing systems of modern multi-span greenhouses. The heavy zinc layer protects against high internal relative humidity, fertilizers, and pesticide chemicals.
Egypt is scaling up its clean energy capacity, centered around projects like the Benban Solar Park. Our rectangular galvanized steel tubes serve as durable support structures for solar trackers. The high torsional rigidity of RHS handles wind loads and abrasive desert sands.
In coastal port facilities at Sokhna, Port Said, and East Port Said, structural steel faces constant saltwater exposure. Hot-dip galvanization with a minimum zinc coating thickness of 85 microns (complying with BS EN ISO 1461) provides the barrier protection required for warehouses and gantries.

Established in 1998, Tianjin Minjie Steel Co., Ltd has developed over more than two decades into a leading manufacturer and exporter of structural steel products. Our production facility spans over 70,000 square meters, strategically located just 40 kilometers from XinGang Port, the largest port in Northern China. This prime location allows us to coordinate prompt shipping schedules directly to key Egyptian maritime hubs like Alexandria, Port Said, and Sokhna.
We manufacture and export an extensive range of pre-galvanized steel pipes, hot-dip galvanized pipes, welded steel pipes, square and rectangular structural tubes, and scaffolding systems. Focusing on research and development, we hold three proprietary patents (groove pipes, shoulder pipes, and victaulic pipes). Our manufacturing facilities include 4 pre-galvanized lines, 8 ERW lines, and 3 advanced hot-dip galvanizing lines, allowing us to align production with international standards, including GB, ASTM, DIN, and JIS. All operations are certified under the ISO 9001 Quality Management System.
With an annual output exceeding 300,000 tons, we have earned municipal recognition for quality control. Our products are exported globally and find applications in heavy machinery, steel structures, agricultural vehicles, automated greenhouses, automotive production, and transport infrastructure.
How our integrated operations ensure delivery schedules and stable pricing for international buyers.
Our quality control program operates continuously from raw material inspection through to final export loading. We inspect raw hot-rolled coils for chemical composition, verify welding integrity with automated eddy current systems, and perform hydrostatic tests to ensure structural reliability.
Located 40 kilometers from XinGang Port (Tianjin), our facility enjoys direct access to container terminals. This proximity lowers local land transport costs and shortens transit times, helping us manage delivery deadlines for construction projects in Egypt.
Equipped with 3 hot-dip galvanizing process lines, we utilize computer-controlled temperature baths to maintain consistent zinc composition. This level of process control ensures uniform alloy layers, minimal zinc slag inclusions, and smooth product finishes.
As international markets emphasize sustainability, Tianjin Minjie Steel is adapting its manufacturing processes to align with global environmental benchmarks. We are optimizing energy usage across our hot-dip galvanizing lines and investigating low-emission zinc-alloy alternatives (such as Zinc-Aluminum-Magnesium coatings) that extend product lifespans while lowering chemical footprints. By implementing high-efficiency heat recovery systems, we aim to reduce our carbon footprint, helping our Egyptian clients meet environmental requirements for international projects.
We regularly host international procurement managers and structural engineers at our Tianjin plant, building long-term business partnerships.
In September 2019, our sales and engineering teams visited clients in Singapore to finalize deliveries of structural hollow sections. The face-to-face meetings helped establish direct communication and align product specs with project requirements.
In 2019, Korean clients visited our facility to review design drawings for structural tubing projects. This physical inspection confirmed our technical capabilities and paved the way for subsequent supply contracts.
An Australian procurement firm visited our facility in November 2018. They conducted an audit of our hot-dip galvanizing lines and weld testing protocols, confirming our compliance with AS/NZS structural standards.
In 2019, an engineering team from India visited several Northern China factories. Following a review of our ISO 9001 certified processes and production capacity, they signed a supply contract for 10 structural container loads monthly.
In June 2017, a Lebanese distributor visited our production plant to check our inventory levels. They placed an order for 1,000 tons of structural steel pipes immediately after the site visit.
After initial discussions at the Canton Fair, a Saudi construction contractor visited our factory in 2018 to evaluate our production capacity. This led to a long-term supply agreement for regional infrastructure projects.
