The earliest known studies of Space Frame Construction systems were those made by Alexander Graham Bell between 1898 and 1908 to form the hulls of some marine and aircraft. Bell aimed to realize these constructions by creating the lightest and strongest structures with tetrahedral geometry.

For more than 100 years, many engineers have worked on the structural details in this area, and many different building types have survived to the present day. The most important of these is Dr. Ing. It is a system developed by Max Mengeringhousen in 1943 and used as the knotting element of high quality steel spheres with full body that passed the literature under the name MERO system. In addition, many construction systems and knot details have been developed and implemented by engineers.

Space cage building systems are systematic and optimum constructions consisting of rod elements and knot elements. The moments are reset in the knots with the principle of joining all the rod elements in the knots and accordingly the calculations are made with the assumption that the rod elements forming the structure operate only against tension and pressure. As a result of these calculations, extremely lightweight and strong roof constructions can be designed.

The basic element that provides the prefabricated structure feature of Space Frame Systems is the concept of modular system that forms the structure. The type of module that forms the structure can be square, rectangular, hexagonal according to the selection made during the design phase.

Space Frame Systems is defined by a module with the following parameters;

Module size in the a = x direction
Module size in b = y direction
h = module depth,
qx, qy = module angles

The choice of modules should take into account economy, manufacturing and assembly facilities, structural analysis requirements under the loads the system is subjected to, geometric conditions (axle spacing, etc.) and aesthetic factors.

Space Frame Structures add the important advantages mentioned below to the projects.

Space Lattice Structures are systems that can fully achieve hyperstatic and three-dimensional load distribution. With this aspect, it is the lightest and most economical roof alternative.
Due to its light weight and 3-dimensional load distribution feature, it transfers less and balanced load to the carrier structure; It is designed more economically in foundations and carrier structure.
It is produced reliably and extremely quickly with manufacturing methods based on industrial and numerically controlled production technologies.
Fast and easy assembly is made.
Service loads to be applied to the roof can be applied with simple details.

EMA ÇELİK realizes the architectural and static designs of the constructions that it will construct in the projects it undertakes with the Architectural Design Office and the Structural Design Office that it employs within itself.

In these projects, EMA ÇELİK considers it important and necessary to carry out all its works in cooperation and coordination necessary for the construction of the work. For this purpose, it is the task of providing the necessary contribution to the necessary cooperation with other project groups at the highest level during the design phase as in every phase of the project.

Within the scope of design studies,

In accordance with the application projects given by the employer;

Preliminary design studies of the system in accordance with the existing architectural design and static requirements
Presenting these studies to the employer and / or project author, conducting alternative studies, if any, and obtaining principle approval
Preparation of the approved front architectural model and the structural model suitable for the requested aesthetics and functions,
Structural analysis, control of results
Sharing the results with the employer and / or project owner, if necessary, by providing alternative solutions, to ensure optimum common solution
With the completion of the solution of the point details
Final projects are submitted for approval to the employer company and / or project developer.

Following architectural suitability and static approval, manufacturing pictures are prepared and manufacturing processes are started.

• EMA ÇELİK carries out all the components of the space frame constructions it produces in its own facilities, with computer-aided manufacturing technologies and under its own quality control procedures.
  Welding processes of the space cage rod elements are done in fully automatic and computer aided welding benches, which make their own length and welding adjustment automatically. The data for the manufacture of the elements to be welded in the machines in question are sent from the central computer, and the axle dimensions are also adjusted numerically. In this way, products that are error-free and almost 100% reliable are produced.
  Spheres are processed entirely by hand, computer aided and numerically controlled benches. Data formatted in files created as a result of structural analysis programs are transmitted to the processing center via computer. Therefore, spheres, which are the most sensitive production point of space cage structures, are processed completely without any errors.
  Intermediate product parts to be used in space cage manufacturing are also produced on CNC machines by the machining method of EMA ÇELİK.
  Supports, lovers profiles, lovers sewing etc. accessories are designed by EMA ÇELİK technical staff and manufactured in accordance with the project.
  Painting and coating processes of all elements are carried out in EMA ÇELİK’s own production facilities. As standard, rod elements are covered with polyester-based powder paint in numerically controlled robot electrostatic powder coating facilities after cleaning in accordance with the technical specifications of purlin struts and profiles.

EMA ÇELİK carries out its manufacturing in accordance with national and international quality standards, and has designed and established the ISO quality management system suitable for the production of space cage systems in order to create an effective inspection system at every stage of its work.

The system in question; It consists of instructions and procedures that describe all processes from purchasing, material supply, storage, manufacturing, tests, shipment, assembly and post-assembly control, starting from the project work.

In order to control and improve the whole system, EMA ÇELİK quality control chief and responsible staff provide continuous and regular service.

To summarize briefly, in accordance with the mentioned quality control system;

All ordering procedures for the supply of necessary materials are made by receiving offers from EMA ÇELİK’s approved suppliers,

The ordered materials are accepted by performing the necessary tests in accordance with the acceptance procedures defined in the purchasing procedures determined within the framework of the quality management system,

During the manufacturing phase, all intermediate controls are inspected by quality control staff and every process is recorded.

Besides physical inspection and measurement controls, mechanical impact and impact-free tests are carried out periodically.

Electrostatic powder coating and metal coating processes are controlled by measuring the coating thicknesses by measuring with numerical measuring instruments, performing mechanical adhesion tests and recording for each baking process.

As a result, every project produced in EMA ÇELİK is produced with a production code and all tests and controls are recorded within the framework of the quality control plan.

All the assembly works in the space cage systems EMA ÇELİK are carried out in accordance with the previously planned and assembly project according to the results of the inspection performed at the assembly site during the preliminary works of the project.

EMA ÇELİK installation officers, for each work, the environmental conditions of the site, the conditions and facilities of the site, the suitability of the assembly team, assembly processes and static requirements, etc. It prepares an assembly project considering all the elements and is planned and carried out in accordance with this project in practice.

Daily work details are recorded with the Daily Activity Report (GFR) and shared with the center. In this way, the project is followed from the center.

At the stages and at the end of the assembly deemed appropriate by the center, EMA ÇELİK technical personnel perform physical inspection, measurement and post-assembly inspections that the work is completed as designed in the project and reported.
