Choosing Chain Link Fencing: Height, Wire Thickness and Mesh Size
November 01, 2026 NewsletterChain link fencing is one of the most common ways to secure sites, warehouses, farms and residential plots in Qatar. It is strong, quick to install and good value. Getting the right specification means looking at four things: height, wire thickness, mesh size and finish.
1. Height
Choose the height by what you need to keep out. Lower fences are fine for marking boundaries and gardens, while construction sites, yards and industrial plots usually need taller fencing. Check whether your site or municipality has a minimum height requirement.
2. Wire thickness
Thicker wire makes a stronger fence that is harder to cut or push through and lasts longer. For security fencing around sites and warehouses, choose a heavier wire. For gardens and light-duty boundaries, a lighter wire is usually enough and costs less.
3. Mesh size
The mesh size is the size of the diamond-shaped opening. Smaller openings are harder to climb and keep out smaller animals, but use more wire per metre. Larger openings are lighter and more economical where climbing is less of a concern.
4. Finish
Galvanised wire resists rust, which is important in Qatar's humid and salty air, especially near the coast. Ask us which finishes are currently in stock.
Planning your order
- Measure the full length of the boundary, including any gates.
- Decide the height, wire thickness and mesh size.
- Plan posts, line wire and fixings along with the mesh rolls.
- Add a little extra for joins and overlaps.
Give us your total length and the specification you need, and we will confirm stock and price.

ASTM, BS, DIN, EN: What Steel Standards Mean When You Order
November 01, 2026 NewsletterSteel drawings and specifications in Qatar often quote a standard such as ASTM A36 or EN 10219. These codes tell everyone exactly what material is required. Understanding them helps you order the right steel the first time.
The main families of standards
- ASTM is published by ASTM International in the United States. Common examples are ASTM A36 for structural steel shapes and plates, and ASTM A500 for cold-formed structural hollow sections.
- EN standards are European Standards. Examples are EN 10025 for hot-rolled structural steel (grades such as S275 and S355) and EN 10219 for cold-formed welded hollow sections.
- BS standards are British Standards. Many older BS steel standards have been replaced by European equivalents with the prefix BS EN, so you will often see codes such as BS EN 10025.
- DIN standards come from Germany. Many have also been replaced by EN standards, but DIN references still appear on older drawings and some products.
Why the standard matters
A standard fixes the steel's strength, chemical composition, dimensions and tolerances. Two beams that look identical can perform differently if they are made to different standards or grades. Consultants specify a standard so the structure behaves as designed.
How to order correctly
- Quote the standard and grade from your drawing, for example "EN 10219 S355" or "ASTM A500 Grade B".
- Give the section size, thickness and length.
- If your project needs documents, ask for the mill test certificate when you place your order.
- If a drawing quotes an older BS or DIN standard, ask us about the equivalent material in stock.
Al-Ahmadi Trading supplies steel products to international specifications including ASTM, BS, DIN and EN. Tell us the standard your project requires and we will confirm what we can supply.

Single Skin or Double Skin Sandwich Panels for Warehouses?
November 01, 2026 NewsletterRoof and wall panels decide how comfortable, efficient and long-lasting a building will be. For warehouses, workshops and site buildings in Qatar, the main choice is between single skin sheets and double skin sandwich panels.
Single skin panels
Single skin panels are profiled steel sheets on their own. They are light, quick to install and economical, which makes them a good fit for:
- open-sided sheds, canopies and car park shades
- storage areas where temperature is not a concern
- temporary or short-life buildings
On their own they give little protection from heat, so the space underneath will be close to outdoor temperature in summer.
Double skin sandwich panels
A sandwich panel has two steel skins with an insulating core bonded between them. In Qatar's climate that insulation makes a real difference:
- Cooler buildings and lower energy bills: the core slows heat entering the building, so air conditioning works less hard.
- Less condensation: the inner skin stays closer to room temperature, which reduces dripping inside.
- Quieter interiors: the core dampens rain and outside noise.
- A finished interior face: no separate inner lining is needed.
They are the usual choice for warehouses that store goods sensitive to heat, workshops, offices, labour accommodation and cold rooms.
Choosing the right panel
Think about what the building will be used for, how much heat you need to keep out and how long the building should last. Core material and thickness affect insulation and fire performance, so check what your consultant or civil defence approval requires before ordering.
Send us your roof and wall areas, the panel type and the thickness you need, and we will advise on what is available.

Galvanised or Black Steel Hollow Sections in Qatar's Climate
November 01, 2026 NewsletterSquare, rectangular and round hollow sections are used everywhere in Qatar, from shades and handrails to gates, frames and light structures. One of the first decisions is the finish: pre-galvanised or black (uncoated mild steel). Qatar's heat, humidity and salty coastal air make this choice more important than it is in many other places.
Pre-galvanised sections
Pre-galvanised tubes and hollow sections are made from steel that already carries a zinc coating. The zinc protects the steel underneath from rust, so these sections:
- suit outdoor, light-duty work such as fencing frames, shades, canopies and racking
- save time, because they do not need painting before use
- look clean and uniform when installed
Remember that cutting and welding remove the zinc at those points. Treat every cut end and weld with a zinc-rich paint so rust does not start there.
Black hollow sections
Black hollow sections have no protective coating. They are usually the more economical option and are ideal when:
- the work will be painted or powder-coated after fabrication
- the steel will be indoors or enclosed
- the frame will be heavily welded, where pre-galvanised coating would be lost anyway
Outdoors, black steel must be properly cleaned, primed and painted, otherwise it will rust quickly in Qatar's humidity.
What about heavy outdoor structures?
For heavily loaded or highly exposed structures, many projects fabricate in black steel and then hot-dip galvanise the finished pieces, which coats every surface, inside and out. Your engineer or consultant will specify which protection your project needs.
Tell us the section shape, size, wall thickness, length and finish you need, and we will confirm availability and price.

C Purlins or Z Purlins: Which Does Your Roof Need?
November 01, 2026 NewsletterPurlins are the horizontal members that carry roof sheets and wall cladding back to the main frame of a building. In Qatar's warehouses, sheds and site buildings, the choice usually comes down to two shapes: C purlins and Z purlins. Both are cold-formed from galvanised steel, but they suit different jobs.
C purlins: simple spans and wall girts
A C purlin has a web and two flanges facing the same way, like the letter C. Each length sits between two supports on its own, which makes C purlins:
- a good fit for shorter, single spans between rafters or columns
- common as wall girts and for framing around doors and openings
- quick to handle, fix and replace on smaller structures
Z purlins: longer, continuous runs
A Z purlin's flanges point in opposite directions. That shape lets one length overlap, or lap, the next over a support, so a row of Z purlins behaves like one continuous member. This makes Z purlins:
- better suited to longer spans and multi-bay roofs
- often more efficient in steel weight on large roofs, because lapped runs share the load over each support
- easier to nest together for transport and storage
How to choose
As a rule of thumb, C purlins are the practical choice for simple single spans and wall framing, while Z purlins are worth considering for larger roofs with several bays. The exact section depth, thickness and spacing should always come from your structural engineer's design, because they depend on the span, roof load and wind load for your site.
When you ask us for a quotation, tell us the profile (C or Z), the section size, the thickness and the lengths you need, and we will confirm what we have in stock.
