The basic parameters that define a Pre-Engineered Steel Buildings are:

Building Width

No matter what primary framing system is used, the building width is defined as the distance from outside of eave strut of one sidewall to outside of eave strut of the opposite sidewall. Building width does not include the width of Lean-To buildings or roof extensions.


Building Length

The distance between the outside flanges of end-wall columns in opposite end-walls is the building length. It is a combination of several bay lengths.


Building Height

Building height is the eave height, which usually is the distance from the bottom of the main-frame column base plate to the top outer point of the eave strut. When columns are recessed or elevated from finished floor, eave height is the distance from finished floor level to top of eave strut.


Roof Slope (x/10)

This is the angle of the roof with respect to the horizontal. The most common roof slopes are 0.5/10 and 1/10. Any practical roof slope is possible.


End bay length

The distance from outside of the outer flange of end-wall columns to centerline of the first interior frame column.


Interior bay length

The distance between the centerlines of two adjacent interior mainframe columns. The most common bay lengths are 6 m, 7.5 m and 9 m.


Design Loads

Unless otherwise specified Zamil Steel Pre-Engineered Buildings are designed for the following minimum loads:

     - Roof Live Load: 0.57 kN/m2

     - Design Wind Speed: 110 km/h


Design for snow loads, earthquake loads, collateral loads, crane loads or any other loading condition, if required must be specified at the time of request for quotation.

Loads are applied in accordance with the latest American codes and standards applicable to Pre-engineered Buildings unless otherwise requested at the time of request for quotation.


Materials produced column, truss and the main structure is made from steel sheet imported from Russia, Japan, South Korea, Taiwan has 345N/mm2 intensity or level 50 or other steels of equivalent standards.
