Under the Dome, Defining New Landmarks in East Africa: Empowering Public Spaces with Our Bespoke Design

图片
  On the skylines of Nairobi, Addis Ababa, and Dar es Salaam, modern municipal buildings are rising. With East Africa’s economic growth and the preparation for major international events and cultural festivals, stadiums, museums, and convention centers are no longer just functional structures – they have become the “calling cards” that showcase a city’s ambition and vitality.   However, when developing such large-scale public buildings, owners and government bodies often face a key challenge: how to achieve unobstructed, large-span spaces while balancing aesthetics and safety? Traditional concrete structures struggle to meet the open-view requirements of stadiums or the artistic fluidity of museums. That is exactly where our expertise comes in. As a team specialized in steel structure design with multiple successfully delivered municipal projects in East Africa, we deeply understand the social significance of these buildings. We provide not just steel structures, but fully tai...

Welded ball processing method

  Welded ball Hot press moulding method Unloading: according to the design requirements, adopt semi-automatic gas cutting, profiling gas cutting, CNC flame gas cutting and other methods to unload the steel plate and cut out the round plate of suitable size, when unloading, it is necessary to reserve the welding shrinkage margin for fabrication and installation as well as the machining margins for cutting, edge planing, milling and so on. Heating: The blanks are heated uniformly to about 1050 ° C ± 50 ° C in a reflector furnace or resistance furnace after unloading. Pressing and moulding: Use hydraulic presses and matching convex and concave moulds to press and mould the heated slabs to produce hemispherical shapes. The demoulding temperature should not be lower than 650 ° C. After the hemisphere is pressed and moulded, the wall thickness should be reduced by not more than 13% and not more than 2.5mm according to the design and specification. Cutting bevel margin: can be processe...

Inspection methods for welds

  welding There are several ways to inspect the weld as follows:   1. Visual inspection: inspection by observing the shape, colour, defects, etc. of the weld with the naked eye.   2. radiological inspection: the use of X-rays or γ-rays on the weld can detect defects within the weld, such as porosity, inclusions and so on.   3. ultrasonic inspection: the use of ultrasonic propagation characteristics, through the ultrasonic scanning of the weld to detect internal defects in the weld, such as inclusions, pores, cracks, etc..   4. Magnetic particle inspection: Coat the surface of the weld with magnetic powder and apply a magnetic field to detect cracks, inclusions and other defects on and near the surface of the weld.   5. Penetration inspection: Coat the surface of the weld with penetrant, and through the penetration and colour development of the penetrant, detect cracks, inclusions and other defects on the surface of the weld.   6. Magnetic Field Inspect...
