Table Of Contents

As the owner of DB Fencing, I have been asked a whole lot of questions from customers who would like to know what it really takes to choose a tubular steel fence. Whether your needs revolve around the sleek appearance of a black metal fence or balancing cost differences compared to the lifespan of a wood fence, these are the most common things you’re going to read about.

What Is a Black Metal Fence Called?

The Black Metal Fence, commonly known as a Steel Fence, Steel Tubular Fence, Steel Spear Fence, or Garrison Fence, is installed to serve not only for fencing but to serve as an important add-on to the aesthetics and security of any premise. This design of fencing is celebrated for durable construction of its pickets, allowing anything from garden fences to pool area security that easily complies with city by-laws.

Applications and Advantages Application: Owing to their flexible nature, black metal fences are applied in gardens, farms, residential areas, highways, railways, balcon, and airports; stadiums, municipal areas, bridges, and stairs. Always such designs remain a hit in settings which demand functionality while appealing to the vision, e.g., villages, communities, gardens, schools, factories, etc., even at residential settings where flowing lines and a modern look of the design increase the value of the property.


  • Quick and effortless installation, significantly reducing labor costs.
  • Harmonious structure that blends well with various environments.
  • A palette of bright colors with a smooth surface, ensuring high tensile strength and toughness.
  • Outstanding in corrosion, static, fading, and aging. It ensures the product shall stay vibrant and structurally strong for the life of the product.
  • Designed to withstand embrittlement and cracking, enhancing longevity.

Common Specifications and Dimensions

Usually constructed of such materials as a square steel pipe, wrought iron, or cast iron, it comes in the dimension of 1800mm x 2400mm, 2100mm x 2400mm, or can be customized to fit specific requirements. It is processed through a multi-stage coating: powder coating and hot-dipped galvanization for extra-strength against corrosiveness. It gets its flawless finish courtesy of advanced welding technology.

  • Upright Pipes: 25mm x 25mm x 1.20mm
  • Rails: 40mm x 40mm x 1.60mm
  • Post: 65mm x 65mm x 2.00mm x 3000mm

These fences come in the preferred color of powder coated stain black. It also comes in grey and white colors to be able to add a bit of taste to the home to match it with the aesthetics of the property.

Popular Regions and Craftsmanship

The black metal fences are one of those in demand, and the fact that it is most demanded only denotes that it is not only beautiful but also secure. This art consists of punched pipes and welding, focusing on sensitive designs that nature-friendly, installation-friendly, provide elegance, and have durable features. Its installation is purposely simply designed for easy installations by individuals or contractors.

Packaging and Maintenance

The black metal fencing is soundly packed with considerations of safe transportation and installation; it is less maintenance-requiring in that which it attracts. Using galvanized steel or aluminum as the base materials, coated with a tough powder-coated paint finish, these fences can take the weather and wear with very little needed by way of upkeep to last many years with appearance and function intact. In a nutshell, to go for a black metal (steel tubular) fence is to embrace security, aesthetics, and a combination thereof with durability. From housing limits and public premises to commercial properties, these fences ensure accommodation of a varied range of needs with the promise of years of life while they remain easily maintainable.

What Is Black Fence Made Of?

Fences are made from prime-quality tubular steel Q235, carefully treated to enhance durability and protection from the outdoor elements, with the classic black finish to add beauty.

Q235 steel is a commonly used carbon structural steel in the construction industry and for making metal products, including tubular steel fences. Its popularity stems from its good performance in structural applications, affordability, and weldability, making it suitable for various manufacturing processes. Here’s a detailed look at its chemical composition, tensile strength, and yield strength to demonstrate why Q235 is an appropriate choice for tubular steel fences:

Chemical Composition of Q235

The chemical composition of Q235 steel is what gives it its specific properties, making it suitable for a wide range of applications. Here is a breakdown of its main components:

  • Carbon (C): 0.12% to 0.20% – The low carbon content ensures good weldability and formability.
  • Manganese (Mn): 0.30% to 0.70% – Enhances the steel’s strength and hardness, which is crucial for structural components.
  • Silicon (Si): ≤ 0.30% – Plays a key role in strengthening the steel.
  • Sulfur (S): ≤ 0.045% – Kept low to improve the steel’s quality.
  • Phosphorus (P): ≤ 0.045% – Like sulfur, phosphorus content is kept low to enhance the steel’s durability and resistance to brittleness.
  • Tensile Strength and Yield Strength of Q235 Tensile Strength: The tensile strength of Q235 steel typically ranges from 370 to 500 MPa (Megapascals), which indicates the maximum stress that the steel can withstand while being stretched or pulled before breaking. This high tensile strength is beneficial for fences that need to withstand force or impact.
  • Yield Strength: Q235 steel’s yield strength, which measures the force required to start deforming the steel, ranges from 235 MPa in its raw form. This property ensures that the steel can bear significant weight and stress without permanent deformation, making it ideal for supporting structures such as tubular steel fences.

Why Q235 Is Suitable for Tubular Steel Fences?

  • Durability: The combination of its chemical composition and mechanical properties makes Q235 steel highly durable and capable of withstanding environmental stress, making it ideal for outdoor structures like tubular steel fences.
  • Weldability: Q235’s low carbon content ensures that it can be easily welded, allowing for the fabrication of complex fence designs without compromising the material’s structural integrity.
  • Strength: Its excellent tensile and yield strengths mean that fences made from Q235 steel can provide a robust barrier, offering a high level of security against potential intruders and effectively resisting impact.
  • Cost-effectiveness: Besides its technical advantages, Q235 steel is also affordable, which makes it an economical choice for large-scale fencing projects without sacrificing quality or security.

Given these characteristics, Q235 steel stands out as a prime material choice for manufacturing tubular steel fences, offering a reliable security guarantee while also being cost-effective and adaptable to various design requirements.

Does Black Steel Fence Rust?

Properly coated and maintained, tubular steel fences powerfully resist rust. Galvanizing and powder coating are the secrets that can make your fence last through time.

At DB Fencing, we guarantee that our high-quality steel fences will not rust for 15-20 years. Our commitment to quality ensures that our products withstand the test of time, even in harsh weather conditions like the rainy season.

Why Our Fences Stay Rust-Free:

  • 360-Degree Full Welding Process: This technique ensures there are no weak points for moisture to seep through and cause rust. Full welding means that acid chemicals from rainwater don’t accumulate at weld points and then drip to the ground.
  • Galvanization and Coating: Our fences are thoroughly coated, with zinc layers and paint adhering securely to all panel surfaces. The hot-dip galvanizing process uses 99.99% pure zinc ingots and follows a detailed procedure including degreasing, washing, pickling, fluxing, drying, galvanizing, finishing, cooling, passivating, and inspection to ensure flawless coverage. This meticulous process ensures that every step is standardized and mechanized for perfection.
  • Powder Coating Process: We use internationally recognized AkzoNobel powder as our raw material, controlling the temperature precisely to enhance adhesion. This ensures the powder coating firmly bonds to the product surface, providing an additional layer of protection against the elements.

With DB Fencing, you’re not just purchasing a fence; you’re investing in long-lasting security and beauty for your property, backed by our promise of durability and resistance to corrosion.
