Welcome To Peru Client’s Engineer To Visit Dorian Factory And Discuss The Project Details

Project dimension: 64*175*9m with divisions for different function + 12*32*8m cold storage room

Project location: Lima, Peru

Project function: Processing, warehouse and cold storage room

The client is specialises in frozen foods of industry with a branch company in China, and importing and exporting kinds of frozen foods. In order to expand his business, he inquired about a 384m2 small cold rooms and a 11,200m2 of steel structure building to Dorian in October. The small cold room project will be purchased within this year and big project will be ordered next year. In order to discuss the modification details better, and understand the strength and scale of Dorian factory, the client arranged his engineer to came to China.  

The project details:

Dorian team took about three days of time to finish layout drawing and quotation after confirm the project details.

The detailed dimension of big project is 64*175*9m, Dorian engineer designed double span for 64m side, with 32m for each span. The whole building is respectly two phase, The first one will construct one span and then second phase. The 7m columns space for 175m side, 8m for 64m side considering the loading and economical issues. Since client mentioned that he prefer insulation materials, Dorian team suggested adopting rock wool sandwich panels as roof and wall, because he didn’t reveal that this project need cold storage rooms inside and other different division areas, so the whole project was designed based on a regular warehouse.

For the small cold storage project of 12*32*8m, Dorian team designed PIR sandwich panels as roof and wall, the layout drawing was finished only and didn’t calculate price, because client’s engineer would come to discuss the further modification details.

The client’s engineer and staff arrived in the Luoyang city on November 1st, Dorian picked up them in the morning and take them to visit factory directly. Firstly, the project details of 64*175*9m project were been talked, during the process of communication, Dorian team learned that the whole building need to be designed into four areas, respectively reception areas, processing area, warehouse area and cold storage area, but the exact dimensions for each area have to be confirmed with their department after backed to Peru. Except the cold storage area adopt 100mm PIR sandwich panels, other area will use rock wool sandwich panels.

For the small cold storage project, the client also requested second proposal to use metal sheet for the exterior roof and 100mm PIR sandwich panels as interior ceiling and wall for comparing.

The definition and function of Rock wool sandwich panel:

Rock wool board, also known as rock wool insulation and decorative board, is an inorganic fiber board made primarily from basalt through high-temperature melting and processing. It is a new type of insulation, fire-retardant, and sound-absorbing material. The artificial inorganic fibers produced through high-temperature melting and processing give rock wool board the characteristics of being lightweight, having low thermal conductivity, absorbing heat, and being non-combustible.                          

The definition and function of PIR sandwich panel:

Polyisocyanurate (PIR) is used in Sanhemei composite boards. PIR is formed through the trimerization of isocyanurate, introducing a cyclic structure and a high isocyanurate index into the compound, resulting in a dense polyisocyanate. This makes the internal rigid foam more stable and provides high heat resistance and flame retardancy. Experiments have shown that it can withstand temperatures up to 200 degrees Celsius for short periods and up to 160 degrees Celsius for long periods.

PIR foam generally achieves a fire resistance rating of B1, with a water absorption rate of up to 0.9%. Its temperature resistance range is approximately -196℃ to +205℃, all of these performance making PIR composite boards ideal for cold storage applications.

After confirmed all the project details, Dorian team take client to the production workshop, the production process of steel columns and beams, purlines and panels were introduced to the client, because the project is close to the sea and it needs  have anti-corrosion effect, so Dorian recommend two kinds of proposals (epoxy zinc rich paint and hot-dip galvanized) for comparing the cost. Both proposals have corrosion prevention effect, but the performance of hot-dip galvanized will be better and cost will be also higher accordingly .

The client’s engineer was amazed that Dorian factory have so many of production workshops, and the quality of product was also highly praised by client’s engineer, the were pretty satisfied with this visiting.

Dorian team have sent update proposal and quotation to client for his small 12*32*8m project already, and the modification details are waiting for client’s feedback.

Productive visiting in Bulgaria Enhance the trust, facilitate the project, and deepen collaboration 12

Productive visiting in Bulgaria: Enhance the trust, facilitate the project, and deepen collaboration

In 2025, Dorian team went to Bulgaria and visited clients onsite from 21st Sep. to 11th Oct., which has reached various achievements. Not only negotiate in the office, check the onsite project land and facilitate the progress, but also have productive discussions and explore more cooperation opportunities. This wonderful visit established the solid trust between the clients and the Dorian team, and Dorian team also explicitly understood the market conditions in Bulgaria.

Round-table in the client’s office

Dorian team was invited to the client’s office to negotiate the project of 27*110*8m steel structure warehouse. The drawing and quotation had already been designed in advance and offered to the client for checking. In the conference, Dorian team reconfirmed lots of details about profiles, and explained the properties and specifications of materials to make the clients understand the proposal. The designer suggested uing the 100mm rock wool sandwich panels with the PU edge sealing, which not only can satisfy the storage requests from the client, but also enhances the overall quality of the whole building. Then, adjustments were made to some details based on the client's requirements, such as the dimensions of the doors and canopy, to meet the client's practical needs for daily use.

Furthermore, Dorian team discussed the schedule of the installation process, and combined with the application procedure for the building permission in the local area. Accordingly, we arranged the best way and time for producing and shipping, which can help the client save the redundancy costs as much as possible. Meanwhile, base on the local construction conditions, we adjust the delivery time in order to avoid the installation delay due to the climate.

In the final, the client also wants to purchase the other products, like solar panels and the battery (energy products). And they want to seek more supply chain opportunities through us. The project is under the approval stage, and client is prepared to pay the deposit.

Ace vs. Ace, professional technical discussion

Besides the requirements for the building daily using from the clients, the structure proposal is the most significant thing. The client’ s project is about the old building extend and renovate the parts of the old building. Aim to take full use of the spare space between old buildings and reinforce the old building. For this point, the Dorian team followed the client to meet the local constructure engineer.

In advance, Dorian team designed two methods as options for the client to choose from. One is chemical bolts, and another is welding angle steel, to connect the new steel structure frame to the old concrete building. Then, Chief Engineer discussed with the local constructure engineer about the condition constraints and the feasibility of the technical proposal to compare two methods, which one is better for the steel structure solutions that extended the existing old building, and optimized the proposal accordingly.

Finally, this meeting facilitated Dorian team to reach an agreement with the local constructure engineer, which ensured the structural safety as the premise and pushed forward the project to the next stage efficiently.

A Pleasant dining time!

Not only on the office table. Beyond working time, Dorian team built strong friendships with many clients. The team had many unforgettable times, exchanging different cultural backgrounds, sharing different dietary habits—these help us get to know each other better and deeper, and trust grows! Really appreciate the clients taking us to try the local special cuisine.

During the dining time, we also talked about many meaningful topics, such as Dorian’s factory in China, the services it can provide, and Luoyang city—the beautiful and peaceful city where Dorian’s factory is located. Besides providing steel structure, color steel sheet, sandwich panels, The factory can also supply including solar panels, batteries, cranes and other supporting equipments. For the prefabrication steel, we can ensure an output of about 3,000 tons monthly, which is really impressive for the clients.

In the end, there are some other real issues/needs from the client, Dorian team provided the solutions, and had made the agreement for procured project about the works to installation and estimated finished time with client. Meanwhile, the initial proposal for the next project has been under designed.

On-site inspection for the project land

In order to fully realize the real condition of the project, Dorian team went to the project land and checked all the details that may affect the new steel structure building. We inspected the existing building to make sure the new building will be erected next to the old one in a proper way.

Including the arrangement between the old and new foundation, the reasonable gaps between the two buildings to avoid the impact of deformation between each building, and also save costs. The designer checked the size of the project place to consider the subsequent way of accessing for the trucks in order to adjust the layout of the doors and the distance between the steel columns in the most appropriate way, which can be more convenient. Moreover, Dorian team suggested client select the rock wool sandwich panels and fireproof painting to meet the local strict requirements for fire resistance.

By the on-site inspection, client is very satisfied with Dorian’s professional suggestions, and agrees with the final proposal. Now, the client is ready to place the order and discuss the installation period.

Honor to be invited to the Exposition

During the visit, Dorian team had been invited to participate in the 79th International Technical Fair between 24th and 27th September 2025 in Plovdiv, Bulgaria. Many clients with high interest came to booth to check our product information and finished cases about the steel structure building. In just two days, all of the intro files have been distributed, which shows the great popularity. During this period, Dorian team helped many clients to know the feasibility of their project, the general budget, and the initial proposal, which got the approval from the clients. We are very pleased and honored to have the chance to help clients resolve their issues and seek further cooperation opportunities.
