There are various types of crane systems used in industry for various purposes such as EOT overhead crane, Overhung/under-slung crane system, Monorail crane system etc.
Alignment of crane beams is very important, the centers of the crane beam webs should be equal to the centers of the crane wheels, with maximum tolerance. Alignment is achieved by setting each end of the beam to the correct dimension and stretching a line from end to end, alternately, a theodolite can be used if available.
The crane beam brackets have slotted holes to assist in ease of alignment,
if the building has been carefully plumbed, adjustment will be minimal. During alignment install the “T” brackets and shim plates, and install the angle braces form column to beam. Finally once alignment is confirmed, the bolts are fully tightened.
The standard Altis mezzanine framing system consists of a steel deck supported by joists framed onto main mezzanine beams. The economy of a mezzanine system is affected by the applied loads (dead, live and collateral) and mezzanine column spacing. Consult Altis representative for advice on the most economical mezzanine design.
The Mezzanines are erected with the main frames, generally prior to sheeting.
The mezzanines beams are first installed by connecting to the columns with clips and high strength bolts.
The joists are then placed between the beams and connected with clips and mild steel bolts. An edge angle is then screwed at the perimeter of the mezzanine area, prior to laying and screwing the decking panels.
The decking panels are attached by 32mm self drilling fasteners without washers. Openings for stairs and penetrations are framed before fixing the concrete reinforcement.
It is important to advise the concreting crew about placement of concrete, particularly if a pump is to be used. The concrete should be evenly spread; concentrated piles of wet concrete could cause deflection in joists of decking.
All dimensions are in millimeters.
This deep-ribbed type “G” panel is the standard Altis deck panel for mezzanines and floor systems. Although exceptionally strong, this panel is used as shuttering for mezzanine reinforced concrete floors and panel is not a substitute for the reinforcement of mezzanine concrete slabs.
The Main Frames (Primary Members) are the main support members and carry the
main load of the Pre-Engineered Building. Altis PEB frame consists of tapered columns and tapered
The columns and rafters are fabricated using the state of technology at Altis Industries. The shape and size of members varies based on the application and requirement.
We strictly follow all the International codes and Standards such as AISC, AISI, MBMA and IS for the design of PEB Sections and welded members.

Colour Coated Galvalume Sheets / Bare Galvalume Sheets
Profile Sheets used for sheeting purpose are generally of ribbed steel sheets used as roof and wall sheeting, roof and wall liners, partition and soffit sheeting.
Profile Sheets used by us are generally of 0.47mm, 0.50mm, 0.55mm thickness and have minimum yield strength of 345 MPa. Profile sheets are hot dipped and galvanized with zinc or zinc-aluminum coating.

Sandwich panel/puff panel are thermally insulated composite building elements for roof and wall cladding in buildings, they consist of an inner and outer galvanised sheet metal cover, coated on one side. Sandwich panel/puff panel are used in industrial construction i.e. construction of industrial halls, cold storage facilities, Textile units, pharma industries etc…

Polycarbonate Sheets are made up of polycarbonate polymer which is durable, high impact-resistant, scratch-resistant and heat-resistant. With good insulation properties and excellent UV protection, these sheets are the perfect way to enhance home and outdoor living spaces sky lights.

Secondary structural framing refers to purlins, girts, eave struts, wind bracing, flange bracing, base angles, clips and other miscellaneous structural parts.
Purlins, girts and eave struts are cold formed steel members which have a minimum yield strength of 345 MPa (50,000 psi) and will conform to the physical specifications of ASTM 572 (Grade 50) or ASTM A653 (Grade 50) or equivalent.
|1||PURLINS & GIRTS||Purlins and girts are roll formed Z sections, 200 mm deep with 64 mm flanges shall have a 16 mm stiffening lip formed at 45˚ to the flange. They are supported on columns, rafters or building walls. They can be lapped and nested at the supports which creates a continuous beam configuration. They are placed on the roof and perimeter of the building. Hence they serve as a support to the roof sheeting and wall cladding.|
|2||C SECTION||C-Sections are 200 mm deep with a 100 mm flange. The flanges are perpendicular to the web and have a 24 mm stiffening lip.|
|3||EAVE STRUT||Eave struts are 200 mm deep with a 104 mm wide top flange, a 118 mm wide bottom flange, both are formed parallel to the roof slope. Each flange has a 24 mm stiffener lip. These are located along the sidewall; at the intersection of the planes of the roof and wall. It is constructed from cold formed C-Section and is rolled to suit the roof slope. This member transmits longitudinal wind force on the end walls from roof brace rods to wall brace rods.|
|4||OPEN WEB JOISTS||These are long span load carrying trusses suitable for direct support of floors and roof decks in the buildings. The system consists of crimped angles welded to the top and bottom chords.|
|5||CABLE BRACING||Cable bracing is made of extra high strength seven strand cable and can be designed to accommodate any length to ensure the stability of the building against forces in the longitudinal and lateral direction due to wind, cranes and earthquakes. It is made of a cable which is forged into a rod terminal and this arrangement is then fixed on a structure using a hill side washer, nut washer and a nut.|
