1 STAGE PLATFORMS Modular stage platforms are made of light alu min profiles. The system comprises portable platforms 1,0m x 2,0m which can be places at different height, from1,0 m up to 1,8m. Supporting feet make it possible to put the stage on the site, in the open air. The structure is provided with auxiliary items, such as stairs, handrails etc. The floor is made of waterproof plywood, either varnished or covered with anti-skid layer.

2 The stage platforms can be put up to make: - stages - bandstands, - catwalks - podiums - exhibition stands etc. Size Telescopic legs.

3 Platform frame is built with specially designed lightweight aluminum profiles with a height of 11 cm, which has grooves section allowing them to use different handles, such as: - Self-handles landings connecting which with each other - Handles the mounting railings, stairs, banners, etc. Picture 1. Picture 2. Picture1,2. Aluminium Frame Picture 3. Picture 3. Frame corner Frame corners platform are made of sheet steel provides a strong platform designed clamping legs, fast and trouble-free assembly does not require physical effort. The corners also have a special basis for protection during transport platform and the protective backing is placed on the platforms as well.

4 Telescopic legs 4. Picture nr 4. Telescopic Legs Telescopic leg is made from specially designed with a lightweight aluminum profile, which allows for fluid and precise height adjustment of platform and thus the platform in a very different ground. System was based on unified platforms, or set at various heights. The use of the base (with plastic rubber feet) makes it possible to static positioning platform.

5 ADJUSTABLE STAIRS Adjustable stairs are quick easy to assemble. They are designed in such a way that could be used with AL-SPAW stage platforms. They can be adjust to the height from 0,9m to 1,8. Additionally, the steps are made of durable profiles covered with non slip water resistant birch plywood or sheet aluminum plate. High quality deck, developed for high frequency use and high demand circumstances. In and outdoor use. Anti skidding top layer.

7 STATIC CALCULATIONS OF STAGE PLATFORMS Taking care of our customers safety Al-Spaw company makes all static calculations by independent engineers. Latest calculations are made using finite element method (FEM). The finite element method (FEM) (sometimes referred to as finite element analysis) is a numerical technique for finding approximate solutions of partial differential equations (PDE) as well as of integral equations. The solution approach is based either on eliminating the differential equation completely (steady state problems), or rendering the PDE into an approximating system of ordinary differential equations, which are then numerically integrated using standard techniques such as Euler's method, Runge-Kutta, etc. In solving partial differential equations, the primary challenge is to create an equation that approximates the equation to be studied, but is numerically stable, meaning that errors in the input data and intermediate calculations do not accumulate and cause the resulting output to be meaningless. There are many ways of doing this, all with advantages and disadvantages. The Finite Element Method is a good choice for solving partial differential equations over complex domains (like cars and oil pipelines), when the domain changes (as during a solid state reaction with a moving boundary), when the desired precision varies over the entire domain, or when the solution lacks smoothness. For instance, in a frontal crash simulation it is possible to increase prediction accuracy in "important" areas like the front of the car and reduce it in its rear (thus reducing cost of the simulation); Another example would be the simulation of the weather pattern on Earth, where it is more important to have accurate predictions over land than over the wide-open sea. 1.
