Pre-Engineered Building (PEB) Structures
Pre-Engineered Building (PEB) structures represent a revolution in modern construction, offering versatility, efficiency and durability. These structures are meticulously designed and fabricated off- site, with all components manufactured to precise standards. The result is a seamless integration of components on-site, reducing construction time significantly.
PEB structures excel in various applications, from industrial and commercial spaces to warehouses and recreational facilities. They are tailored to meet specific requirements, offering a range of customization options in terms of design, layout and finishes. With an emphasis on cost- effectiveness, PEB structures often involve fewer materials and labor compared to traditional construction methods, making them an environmentally friendly choice.
Designed to withstand varying weather conditions, seismic forces and other challenges, PEB structures showcase exceptional strength and longevity. These structures combine engineering precision and technological advancements, resulting in aesthetically pleasing, functional and reliable spaces that fulfill the demands of modern construction projects.
Commonly utilized for architectural exterior cladding, ceilings, fences, driveways, and grilles. Expanded metal mesh offers durability and strength surpassing lighter wire mesh. Its small openings enable airflow, water passage, and light transmission while barring larger objects. Unlike standard sheet metals, exposed edges enhance traction, making it ideal for display stands and drain covers.

Dimensions used to measure expanded mesh
LWD — Long way dimension of the expanded mesh.
SWD — Short way dimension of the expanded mesh.
LWO — Long way opening of the expanded mesh.
SWO — Short way opening of the expanded mesh.
Strand Width - Length fed between the upper and lower tooling to produce the mesh.
Strand Thickness - The thickness of the material used to produce the standard material is the original thickness. It is also the thickness of the material after flattening the expanded mesh.
Bond - The intersection of the extended punched expanded mesh connections. It is sometimes called as a joint.
Overall Thickness - Expand the thickness of the mesh when laying on a flat surface. In the case of flat materials, the strands and the total thickness are the same.
Perforated metal, commonly known as perforated sheet or screen, is crafted by manually or mechanically stamping, utilizing CNC technology or employing laser/water jet cutting to form holes of varying sizes, shapes and patterns. The materials employed for creating perforated sheet metal encompass stainless steel, cold rolled steel, galvanized steel, brass, aluminium and other choices.

Flat rolling of expanded mesh is a supplementary procedure aimed at decreasing the overall thickness of the mesh. This flattening process encompasses four primary stages, with specific approaches differing among various Expanded Mesh manufacturers.

Random Shearing: Results in open diamond design and angle, leaving jagged edges and prongs in most cases. A closer tolerance is obtained at a normal mill tolerance for standard and flattened expanded metal of +/- 1.58 mm and +/- 25.4 mm on shearing.
Bond Shearing: Results in closed diamond design and angle, eliminating jagged edges and prongs. Shearing cuts through expanded metal at center of bond, where strands intersect. Standard expanded metal should not be bond sheared SWD. SWD and LWD tolerances are greater at +/-1/2 design size.
Mashrabiya, a blend of islamic window screen and classic jalousie, embodies spirituality, aesthetics and utility, reflecting local cultural essence. Whether in commercial or residential settings, the mashrabiya serves multifarious roles, encompassing light modulation, airflow control, temperature reduction, humidity enhancement and ensuring substantial privacy.

Our purlins are a lightweight & efficient economical support system for framed structures.
C Purlins - Section
- C purlins have equal flanges and are suitable for simply supported spans. C purlins are non-overlapping.
- Non-standard orders are available upon request.
C Purlins - Profile
Z Purlins - Section
Z purlins feature one broad and one narrow flange so that two Z purlins of the same size fit snugly together. Z purlins are ideal for lapping to achieve higher strength for the same section installed in single spans.

Hole Punch & Cleat Details
- E-Mesh Metal’s C and Z purlins are supplied with holes punched (to builder’s requirements) with recommended holes to match cleat details (see illustration below).
- The purlins are designed based on the web to cleat connection of sections.
- Please use purlin detailing sheet when placing an order.
Note:-
- It is necessary to have the top flange of the purlins to point up the slope. This minimizes any rotational tendencies of the purlins.
- D: purlin depth.
- 10 standard hole punch per piece. Additional hole punch subject to additional charges.

Lapping Details
To provide sufficient structural continuity, each end of the lap requires one bolt through the webs, nominal length is the distance between bolt centers at the end of the laps. Laps vary in length with both section size and span, minimum lap should be 10% of the span.
Bolt Details
Bolts are usually M14, M16 (grade 4.6)
Application
C purlins can be used in single or continuous spans but cannot be lapped. Z purlins can be used in single or continuous spans (lapped or unlapped). Lapped continuous spans will increase purlins loading capacity.
Custom cut
E-Mesh high tensile purlins are available in custom-cut lengths, Special transportation arragement and on-site handling equipments are required for purlin lengths more than 12m.
Packing & Transportation
E-Mesh purlins are packed in bundles with weight generally less than 1500kg and strapped with metal strips. Special packing for export requirements are provided upon request.
