ADVANTAGES OF GALVANISED STEEL GRATES

Galvanised steel grates are commonly used in civil construction for a variety of applications. Galvanising is the process of applying a protective zinc coating to steel to prevent it from rusting and corroding. Here are some advantages of galvanized steel grating in civil construction:

1. Corrosion Resistance - Galvanised steel is highly resistant to corrosion and rust, making it an ideal material for outdoor use in civil construction. This means that galvanised steel grates will last longer and require less maintenance compared to other materials.
2. Strength - Steel is known for its high strength-to-weight ratio, making it a strong and durable material. Galvanised steel grates are no exception and can withstand heavy loads without bending or warping.
3. Safety - Galvanised steel grates provide slip-resistant surfaces, which helps prevent accidents and injuries.
4. Aesthetics - Galvanised steel grates come in a variety of designs and can be customised to match the aesthetic of the surrounding environment. This makes them a popular choice for architects and designers in civil construction.
5. Cost-Effective - Galvanised steel grates are relatively inexpensive compared to other materials. They also require less maintenance which can result in cost savings over time.

Overall, galvanised steel grates are a reliable and versatile material in civil construction that offers numerous benefits, including corrosion resistance, strength, safety, aesthetics, and cost-effectiveness.

Civilcast has a broad range of galvanised steel grates in stock, whether you’re looking for sump grates, heelguard grates, drop-in gates, V-grates, gully grates, roll kerb grates, surcharge grates and trench grates to name a few.

Steel Gratings vs Stone Gratings: Which Is Best For You?

Gratings are designed for high impact and high load applications. The most common materials for grates are steel or stone.

Steel gratings are an essential structural component of many builds, particularly in commercial and industrial spaces.

Overall Advantages of Steel Gratings

Steel is used in grating due to the following reasons:

1. Strength:
   Steel has exceptionally high tensile strength. It is a durable alloy that discourages dislocation at an atomic level.
2. Durability:
   Due to its insusceptibility to rot, pests are kept at bay. You can count on steel whether in high heat, extreme cold, gale force winds or torrential rain.
3. Sustainability:
   Steel is one of the most recycled materials in the world. It can be melted down and re-fabricated an infinite number of times without losing its structural integrity and has a global recycling rate of 90%.

Overall Disadvantages of Steel Gratings

However, there are several downsides to steel gratings:

1. Susceptibility to theft:
   Due to the rising value of scrap metal globally, steel grates have often become a target for theft.
2. Susceptibility to rust: There are several types of steel grates, and all of which are susceptible to rust except for stainless steel or galvanized steel.
3. Slippery surfaces: Some designs may be added to increase friction. However, these steel gratings are still very slippery when wet.
4. Higher heat absorption:
   Due to its metallic properties, steel grates tend to absorb and retain heat rapidly.
5. Not aesthetically pleasing:
   Steel gratings generally have limitations on colors and designs and are perceived as more industrial-looking.

Types of Steel Gratings

There are five different types of steel gratings, each with their unique applications and benefits. They are:

Stainless Steel Grating

Stainless steel is versatile and valuable due to its hygienic value and durability. Here are the top benefits of stainless steel gratings:

1. Strength
   Stainless steel can retain its strength at both high and low temperatures.
2. Cleanliness
   It is easy to clean and doesn't support the growth of bacteria.
3. Corrosion Resistance
   It withstands corrosion and rust well.
4. Recyclability
   Stainless steel can be recycled for sustainability.
5. Durability
   Its resistance to corrosion makes it very durable.

However, its biggest drawback is its cost, making it less feasible for many applications.

Cast Iron Grating

Cast iron grating is an economical material that excels in areas with heavy or light wheel loads, offering excellent corrosion resistance but is still susceptible to rust.

Mild Steel Grating

This type of grating can be used in various ways but has weaker tensile strength compared to its counterparts.

Galvanised Steel Grating

Galvanized steel gratings offer a glossy finish and extended service life. Here are some benefits:

1. Extended Service Life
   Galvanized steel can last over 30 years in corrosive environments.
2. Low Maintenance Costs
   It typically doesn't require painting or extensive maintenance.
3. Scratch Protection
   Galvanized steel is protected from scratches during physical contact.
4. Adaptability
   It can be used for any structure of any shape and size.

Aluminum Grating

Aluminum grating is lightweight and corrosion-resistant, suitable for various industrial applications, although its aesthetics may not appeal to all architects.

Overall Advantages of Stone Gratings

While steel gratings are common, many architects prefer stone gratings for their aesthetic appeal. Stone gratings offer:

1. Rust and corrosion prevention
2. Less heat absorption
3. High load sustainability
4. Greater slip-resistance
5. Reduced theft susceptibility

Types of Stone Gratings

There are three types, each with strengths, weaknesses, and applications.

Natural Stone Slabs

These come in various shapes and sizes, though they are less strong and have limited load-bearing properties.

Cast Stone

Known for its aesthetic value, cast stone is often used for decorative features but cannot withstand high loads.

Reinforced Reconstituted Stone

This composite material offers impressive loading performance and aesthetic appeal. Key benefits include:

1. Color Matching
2. Added Value to Developments
3. Cost-Effectiveness
4. Efficient Delivery
5. Quality Consistency
6. High Loading Performance
7. Increased Safety

Concluding Remarks

Both stone and steel gratings offer distinct advantages. Be aware of the costs involved to ensure your design comes to life.
